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).

An enantioselective Mannich reaction between 3-fluorooxindoles and pyrazolinone ketimines has been developed for the construction of amino-pyrazolone-oxindoles containing stereogenic C-F units. Based on this new protocol that allows for the generation of two adjacent tetrasubstituted stereocenters, a variety of structurally diverse fluorinated amino-pyrazolone-oxindoles were obtained in good to excellent yields with excellent diastereoselectivities and enantioselectivities (up to 98% yield, >20 : 1 dr and >99% ee). What’s more, good yield and high stereoselectivities were obtained in the gram-scale reaction.

CO2 capture by ionic liquids has been successfully achieved, indicating that the adsorption of CO2 plays an important role in the activation and transformation of CO2. In this work, highly efficient capture of CO2 is investigated with several novel ILs, which were prepared from bicyclic amidine (DBN) with pyrazole derivatives. Among the kinds of DBN-based ILs, it is found that the optimal absorption capacity (0.93 mol CO2/mol IL) can be achieved by [DBNH][3-MethylPyr] at 40 degrees C and atmospheric pressure. In view of analysis, the significant increase in CO2 capacity was affected by the reactivity of activated nitrogen, steric hindrance and the type of substituents. On the basis of the spectroscopic investigation and Density Functional Theory (DFT) calculation, the absorption mechanism was illustrated, it was verified that anions can react with CO2 to form carbamates. Meanwhile, charge analysis reasonably elucidated the diversity of absorption capacity in various ILs. It suggested that electric-charge distribution of activated nitrogen in pyrazole ring system can play an important role in determining the reaction of ILs with CO2. Consequently, DBN-based ILs can be excellent candidates for CO2 capture. (C) 2020 Elsevier B.V. All rights reserved.

The first Pd-catalyzed asymmetric allenylic [4+1] cycloaddition was successfully developed. Alternatively, tuning the Pd catalyst switched the reactivity toward an unprecedented [4+3] cycloaddition/cross-coupling. Ligands play a vital role in controlling the reaction pathway, allowing highly selective access to different products from identical substrates. Biological evaluation of the obtained compounds led to the discovery of new antitumor targets. A possible mechanism is proposed, suggesting two interesting catalytic cycles for the cycloaddition with palladium-butadienyls. This study also demonstrated the potential and utility of allenic esters as 1,4-biselectrophiles and C-4 synthons for participating in cycloaddition reactions.

I found the field of Chemistry; Science & Technology – Other Topics very interesting. Saw the article Reductive dehalogenation and dehalogenative sulfonation of phenols and heteroaromatics with sodium sulfite in an aqueous medium published in 2019.0.

Prototropic tautomerism was used as a tool for the reductive dehalogenation of (hetero) aryl bromides and iodides, or dehalogenative sulfonation of (hetero) aryl chlorides and fluorides, using sodium sulfite as the sole reagent in an aqueous medium. This protocol does not require a metal or phase transfer catalyst and avoids using organic solvent as the reaction medium. This method is especially suitable for substrates that readily tautomerize (such as 2-or 4-halogenated aminophenols and 4-halogenated resorcinols), for which dehalogenation or sulfonation proceeds under mild reaction conditions (<= 60 degrees C). As sodium sulfite is an inexpensive, safe, and environmentally less hazardous reagent, this method has at least three potential applications: (i) in the deprotection of halogens as protecting groups, using sodium sulfite as a reducing agent; (ii) in the sulfonation of aromatic halides under mild reaction conditions avoiding hazardous and corrosive reagents/ solvents; and (iii) in the transformation of toxic halogenated aromatics into less harmful compounds.

Iridium-catalysed catalytic, regioselective C-H borylation of beta-aryl-aminopropionic acid derivatives gives access to 3,5-functionalised protected beta-aryl-aminopropionic acid boronates. The synthetic versatility of these new boronates is demonstrated through sequential one-pot functionalisation reactions to give diverse building blocks for medicinal chemistry. The C-H borylation is also effective for dipeptide substrates. We have exemplified this methodology in the synthesis of a pan alpha(v)integrin antagonist.

Ampelocalamus scandens is native to Guizhou Province, China, and grows at an altitude of 260-320 m. It can be used as a raw material for weaving and papermaking. In the current study, the complete chloroplast (cp) genome of A. scandens was sequenced and is reported for the first time. The complete cp sequence was 139,504 bp, include large single-copy (LSC), small single-copy (SSC), and a pair of invert repeats (IR) region of 83,103 bp, 12,813 bp, and 21,793 bp, respectively. Besides, the plastid genome comprised a total of 132 genes, including protein-coding, tRNA, and rRNA genes as 85, 39, and 8 genes, respectively. Phylogenetic analysis based on 28 cp genomes reveals that A. scandens is closely associated with Ampelocalamus melicoideus in Arundinarodae.
