Four new derivatives of the versatile polyfunctional ligands 3-(pyrazol-1-yl)propanamide (1, = PPA) and 3-(3,5-dimethylpyrazol-1-yl)-propanamide (2, = Me(2)PPA) have been prepared, in which one of the amide hydrogens on 1 and 2 is formally replaced by alkyl residues. X-Ray diffraction studies revealed that, in contrast to 1 and 2, the N-isopropyl substituted derivatives 3 and 4 form supramolecular hydrogen-bonded chains rather than two-dimensional arrays, and the N-(2-methyl-4-oxypentan-2-yl) (=MOP) substituted compounds 5 and 6 exist as cyclic dimers in the solid state. Reactions of PdCl2(COD) (COD = 1,5-cyclooctadiene) with 2 equiv. of the corresponding ligands 1-6 in all cases afforded trans-PdCl2(L)(2) complexes (7-12). X-ray crystal structure determinations of 8, and 10-12 revealed kappa N-monodentate coordination of the PPA-type ligands. (C) 2019 Elsevier Ltd. All rights reserved.

Linear alkanes are essential building blocks for natural and artificial assemblies in water. As compared with typical, linear alkane-based micelles and recent aromatic micelles, we herein develop a cycloalkane-based micelle, consisting of bent amphiphiles with two cyclohexyl frameworks. This uncommon type of micelle, with a spherical core diameter of similar to 2nm, forms in water in a spontaneous and quantitative manner. The cycloalkane-based, hydrophobic cavity displays peculiar host abilities as follows: (i) highly efficient uptake of sterically demanding Zn(II)-tetraphenylporphyrin and rubrene dyes, (ii) selective uptake of substituted Cu(II)-phthalocyanines and spherical nanocarbons, and (iii) uptake-induced solution-state emission of [Au(I)-dimethylpyrazolate](3) in water. These host functions toward the large metal-complex and other guests studied herein remain unaccomplished by previously reported micelles and supramolecular containers.

Acid-sensing ion channels (ASICs) are a family of ion channels permeable to cations and largely responsible for the onset of acid-evoked ion currents both in neurons and in different types of cancer cells, thus representing a potential target for drug discovery. Owing to the limited attention ASIC2 has received so far, an exploratory program was initiated to identify ASIC2 inhibitors using diminazene, a known pan-ASIC inhibitor, as a chemical starting point for structural elaboration. The performed exploration enabled the identification of a novel series of ASIC2 inhibitors. In particular, compound 2u is a brain penetrant ASIC2 inhibitor endowed with an optimal pharmacokinetic profile. This compound may represent a useful tool to validate in animal models in vivo the role of ASIC2 in different neurodegenerative central nervous system pathologies.

A new series of 2,4-dimethyl-1H-pyrrole-3-carboxamide derivatives bearing benzimidazole moiety was synthesized through a molecular hybridization approach and evaluated for in vitro anticancer activity by NCI-60 on leukemia, melanoma, lung, colon, CNS, ovarian, renal, prostate and breast cancer cell lines at a single dose (10 mu M). Among all the synthesized conjugates, some derivatives showed more or less good activity even at such a small dose, while, compound 5-(1H-benzo[d]imidazol-2-yl) N (1-cyclohexylethyl)-2,4-dimethyl-1H-pyrrole-3-carboxamide (80 displayed significant antiproliferative activity specifically against MDA-MB human cancer cell lines. Compound 8f showed promising activity against MDA-MB-435 cell line of melanoma (Growth inhibition: 62.46%) and MDA-MB-468 cell line of breast (Growth inhibition: 40.24%). Computational ADME study qualified its significant physicochemical, pharmacokinetic and drug-likeness properties with good predicted oral bioavailability. Thus this new hybrid molecules would be useful for further anticancer drug development.

Reactions of 2-[1-(3,5-dimethylpyrazol-1-yl)ethyl]pyridine (L1) and 2-[1-(3,5-diphenylpyrazol-1-yl)ethyl]pyridine (L2) with the [Pd (COD)Cl-2] or [Pd (COD)MeCl] produced palladium (II) complexes [Pd(L1)ClMe] (1), [Pd(L1)Cl-2] (C2), [Pd(L2)ClMe] (3), and [Pd(L2)Cl-2] (4) in quantitative yields. Solid state structures of complexes 1, 3 and 4 established the formation of mononuclear compounds, containing one bidentate ligand unit per metal atom, to give square planar complexes. All the other spectroscopic characterization data and elemental analyses were consistent with the observed structures. All the palladium (II) complexes 1-4 gave active catalysts in the methoxycarbonylation of 1-octenes. The catalysts demonstrated 100% chemoselectivities towards esters and favored the formation of linear isomers. Reaction conditions such as the type of phosphine derivative, acid promoter, solvent system, time, pressure and temperature have been investigated and shown to affect both the catalytic activity and regio-selectivity of the catalysts. Solid-angle modelling established the comparable steric contributions from the ligands, consistent with the similar regioselectivities of the resultant catalysts.

Application In Synthesis of 3,5-Dimethyl-1H-pyrazole. The Name is 3,5-Dimethyl-1H-pyrazole. Through research, I have a further understanding and discovery of 67-51-6.

The reaction of sym-bis(P-chlorodiphenyl)-carbodiphosphorane (1) with difunctional nucleophiles leads to carbodiphosphoranes carrying two additional chelating N-donor functionalities. A proof of concept is demonstrated by the synthesis and characterization of sym-bis(3,5-dimethyl-1H-pyrazol-1-yl)-carbodiphosphorane (CDP((3,5-Me)Pz)(2), 2) and sym-bis(pyridin-2-yloxy)carbodiphosphorane (CDP(O-Py-2)(2), 3). Due to their superbasic central two-/four-electron carbon donor functionality, these neutral ligands are electronically flexible to act as neutral six-or eight-electron donors, as pincer ligand templates, or as two geminally metal bridging ligands. Their potential to form monoand dinuclear complexes involving two 6-ring or two 5-ring N,C-chelate ring motives has been explored. Complexes of 2 and 3 with fac-[M(CO)(3)] fragments (ls d(6); M = Cr, Mo, W) were used as spectroscopic probes. They reveal a strong sigma-donor and potential pi-donor ability of the central carbon donor pushing electron density for enhanced M-CO back-bonding into the metal d orbitals. DFT calculations consolidate this observation. Dinuclear and multinuclear d(10) Cu(I) complexes have been formed and structurally investigated upon treating these CDP ligands 2 and 3 with CuX (X = Cl, Br, I).

Formula: C5H8N2. I found the field of Chemistry very interesting.

A pyridine-pyrazole-pyrene-based chemosensor,L, has been developed and fully characterized by all the possible techniques (ESI-MS, NMR, CHN, IRetc.). It has been found that the probe,L, selectively recognizes Cu(2+)ion and Fe(3+)ion fluorogenically and chromogenically, respectively, among a wide range of competitive metal ions. It has been demonstrated that the probe is not only metal ion-selective but also oxidation state-selective for Fe(3+)ions. The metal complexes (Cu and Fe) of the ligand were synthesized and characterized using different spectroscopic techniques and they were also characterised X-ray structurally as well, which confirm the stoichiometry (L : M = 2 : 1). The sensitivities for the fluorogenic sensing of Cu(2+)ions and chromogenic sensing of Fe(3+)have been found to be as low as nano molar level detection (69 nM and 27 nM, respectively). Further studies reveal that the Cu(II)L(2)complex can act as a turn-off fluorescent chemosensor for S(2-)ions and Fe(III)L(2)can act as a reversible turn-off colorimetric chemosensor for F(-)ions over other anions.

Saw the article Microwave-assisted pyrolysis of furfural residue in a continuously operated auger reactor: Characterization and analyses of condensates and non-condensable gases published in 2019.0, Reprint Addresses Dai, JJ (corresponding author), Coll Chem Engn, Beijing, Peoples R China.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole.

Microwave-assisted pyrolysis of furfural residue (FR) in an auger reactor was conducted. The biochar yield decreased and non-condensable gas yield increased with increasing temperature. Condensate yield reached maximum (i.e. 21.49 wt%) at 550 degrees C. Kaolin, CaO and K2CO3 enhanced tar secondary reactions, reduced the yield and O/C ratio of bio-oil, improved GC-MS areas of phenolic compounds to 76.25%, 89.28% and 93.1%, respectively. All additives improved yields of H-2 and CH4, while CaO reduced CO2. With increasing temperature, relative proportion (RP) of HCN/NH3 reached up to 13.67, while RP of H2S and chlorine in volatiles increased from 1.17%, 5.97% to 2.75%, 9.00%, respectively. Ammonia nitrogen in volatiles increased to 6.94% by K2CO3. Kaolin improved RP of HCN from 0.11% to 5.47%, while K2CO3 eliminated HCN. H2S increased with kaolin addition and decreased with CaO and K2CO3. Electricity consumption of MWAP varied from 0.5 to 3.78 (kWh/kg FR) depending on temperatures and additives.

Catalyst deactivation caused by the aggregation of active metal species in the reaction process poses great challenges for practical applications of supported metal catalysts in solid-liquid catalysis. Herein, we develop a hypercrosslinked polymer integrated with N-heterocyclic carbene (NHC) as bifunctional support to stabilize palladium in heterogeneous C-C bond formations. This polymer supported palladium catalyst exhibits excellent stability in the one-pot fluorocarbonylation of indoles to four kinds of valuable indole-derived carbonyl compounds in cascade or sequential manner, as well as the representative Suzuki-Miyaura coupling reaction. Investigations on stabilizing effect disclose that this catalyst displays a molecular fence effect in which the coordination of NHC sites and confinement of polymer skeleton contribute together to stabilize the active palladium species in the reaction process. This work provides new insight into the development of supported metal catalysts with high stability and will also boost their efficient applications in advanced synthesis.
