Continuous process for production of CuCF3 via direct cupration of fluoroform

The first continuous flow process has been developed for the synthesis of a superior trifluoromethylating reagent, ligandless CuCF3, from fluoroform, by far the best CF3 source in terms of availability, cost, and atom economy. Optimization of the residence time and feed rates for CHF3 (gas), the cuprating reagent (premade from CuCl and t-BuOK in a 1:2 ratio) in DMF, and the stabilizer (Et3N· 3HF) at 23 °C and atmospheric pressure has allowed for the continuous production of CuCF3 in consistently high yields of up to 94%. The thus produced CuCF3 has been shown to be as highly efficient a trifluoromethylating agent as the one from the previously developed batch process.

Design, synthesis, DFT study and antifungal activity of the derivatives of pyrazolecarboxamide containing thiazole or oxazole ring

Pyrazolecarboxamide fungicides are one of the most important classes of agricultural fungicides, which belong to succinodehydrogenase inhibitors (SDHIS). To discover new pyrazolecarboxamide analogues with broad spectrum and high activity, a class of new compounds of pyrazole carboxamide derivatives containing thiazole or oxazole ring were designed by scaffold hopping and bioisosterism, and 36 pyrazole carboxamide derivatives with antifungal activity were synthesized. Those compounds were evaluated against five phytopathogenic fungi, Gibberella zeae, Phytophythora capsici, Sclerotonia sclerotiorum, Erysiphe graminis and Puccinia sorghi. The results indicated that most of the compounds displayed good fungicidal activities, especially against E. graminis. Theoretical calculations were carried out at the B3LYP/6-31G (d, p) level and the full geometry optimization was carried out using the 6-31G (d, p) basis set, and the frontier orbital energy, atomic net charges, molecular docking were discussed, and the structure-activity relationships were also studied.

Aminocarbonylation of Aryl Halides to Produce Primary Amides by Using NH4HCO3 Dually as Ammonia Surrogate and Base

An efficient and clean protocol was developed for rapid production of primary aromatic amides by aminocarbonylation with NH4HCO3. Without addition of auxiliary base, the use of solid and cheap NH4HCO3 dually as ammonia surrogate and base not only promoted aminocarbonylation over subsequent dehydration and hydrolysis of amides owing to its weak basicity, and it also made the reaction manipulation clean and simplified without the presence of stinky NH3 or organic amines. The Xantphos ligand with relatively intensive π-acceptor character (1J31P–77Se=758 Hz) and wide natural bite angle (βn=111°) was found to be indispensable for the high efficiency of this reaction.
