An operationally simple method to employ nonactivated carboxylic acids as alkylating agents in the N-alkylation of heterocycles is reported through an electrochemically driven anodic decarboxylative process. A wide substrate scope across a range of heterocycles is demonstrated along with a series of applications that significantly reduce the step count required to access such medicinally relevant structures.

The complex [MoO(O-2)(2)(pyrazole)(2)] (1) is an effective catalyst for the oxidation of organic sulfides (methyl-phenylsulfide and diphenylsulfide). Reactions can be run in water as the only medium, at low temperature (25 degrees C), with low catalyst loadings (0.2 mol%) and excellent H2O2 efficiency with no significant non-productive decomposition of the oxidant. Under conditions that favor sulfone formation, the overall process, including isolation of the precipitated product (by filtration or centrifugation) and recycling of the aqueous phase con-taining the catalyst, can be performed in the absence of organic or ionic liquid solvents. Catalytic results with the recycled aqueous phase were the same as those obtained in the first cycle. With water as the sole solvent, 1 is a superior catalyst to the 3,5-dimethylpyrazole complexes [MoO(O-2)(2)(dmpz)(2)] (2) and [Hdmpz](4)[Mo8O25.8(O-2)(0.2)(dmpz)(2)]center dot 4H(2)O (3). Crystal structures for 1 and 3 are presented.

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.

Enantioenriched 1,4-dicarbonyl compounds are versatile synthons in natural product and pharmaceutical drug synthesis. We herein report a mild pathway for the efficient enantioselective synthesis of these compounds directly from aldehydes through synergistic cooperation between a neutral eosinY hydrogen atom transfer photocatalyst and a chiral rhodium Lewis acid catalyst. This method is distinguished by its operational simplicity, abundant feedstocks, atom economy, and ability to generate products in high yields (up to 99%) and high enantioselectivity (up to 99% ee).

Dearomatization of indole derivatives offers a straightforward approach to access diverse indolines. To date, the corresponding dearomative transformations involving electron-deficient indoles are limited. Herein, we report a one-electron strategy for dearomatization of electron-deficient indoles via a photoredox-catalyzed hydroalkylation employing commercially available glycine derivatives as the hydrofunctionalization reagents. Followed by DBU-mediated lactamization, structurally appealing lactam-fused indolines are obtained in good to excellent yields with exclusive selectivity.

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.

Quality Control of 3,5-Dimethyl-1H-pyrazole. Verma, A; Tomar, K; Bharadwaj, PK in [Verma, Ashish; Tomar, Kapil; Bharadwaj, Parimal K.] Indian Inst Technol Kanpur, Dept Chem, Kanpur 208016, Uttar Pradesh, India published Halocarbon Encapsulation via Halogen center dot center dot center dot pi Interactions in a Bispyrazole-Based Cryptand in 2019.0, Cited 36.0. The Name is 3,5-Dimethyl-1H-pyrazole. Through research, I have a further understanding and discovery of 67-51-6.

A novel bispyrazole-based expanded cryptand was synthesized via Schiff base condensation reaction having an internal cavity of 160 angstrom(3) with a hydrophobic nature. The cryptand features electron-rich multiple pyrazole rings for enhanced weak noncovalent interactions with the guest molecules. The host-guest capabilities of the cryptand were investigated for encapsulation of the most inactive halogen bond donor molecules (having small sigma-hole size), namely, CH2Cl2, CHCl3, CCl4, C2HCl3, C2H4Cl2, and C2H4Br2. Analysis of crystal structures clearly revealed that halogen bonding (C-Cl/Br center dot center dot center dot pi (pyrazole)) and hydrogen bonding (C-H center dot center dot center dot pi(pyrazole)) interactions played a key role in stabilizing the halogenated guests inside the hydrophobic cavity of cryptand. At the same time, the cage is efficiently able to exclude hydrophilic solvent molecules, like, water and methanol, suggesting the hydrophobic nature of the cavity. Due to the comparably large sigma-hole in C2H4Br2, it showed the strongest halogen bonding interaction with the host cryptand, while weakest interaction was found for the CH2Cl2 guest which has the smallest size sigma-hole. Furthermore, the cryptand is able to adjust its central cavity according to the size of the guest. The biggest cavity size was found for the C2H4Br2 guest, while smallest size was found for the CH2Cl2 guest molecule. This study sheds more light on the interaction of halogenated solvents via halogen and hydrogen bonding, which is critical in understanding and controlling chemical reactions where solvent effects play an important role.

The study of the relationship between intermolecular interactions present in the solvation process and the magnitude of thermodynamic properties is extended from imidazole to pyrazole derivatives. The enthalpies of solution of pyrazole, 3,5-dimethylpyrazole and 3,4,5-trimethylpyrazole were calorimetrically determined in the solvents water, methanol and acetonitrile. The enthalpy of solution values for the three compounds in the three solvents are endothermic and spontaneous with an increase in entropy. As in the case with imidazole derivatives, the formation of a solution of pyrazole derivatives creates liquids that are more structured thermodynamically. The enthalpy of sublimation for 3,4,5-trimethylpyrazole, which is not available in the literature, was determined by the Knudsen effusion method. The combination of these thermodynamic properties has allowed the corresponding enthalpies of solvation to be obtained for the three pyrazole derivatives in the three selected solvents. With the use of the Pierotti equations and the enthalpies of solvation, the enthalpies of cavity formation were calculated along with the corresponding solute-solvent enthalpies of interaction. The infrared spectra and molecular volumes, as estimated through the electronic density, were used to obtain molecular insights into the solvation sensible sites within the studied solute molecules. The discussion of the solvation process and enthalpies of interaction of the pyrazole derivatives is based on the molecular structural features of solutes, specific intermolecular interactions and protic or aprotic nature of the solvents. The use of any empirical parameters in the discussion of the results was avoided. (C) 2020 Elsevier B.V. All rights reserved.
