Transformation of Amides to Thioamides Using an Efficient and Novel Thiating Reagent
Molecules, 2022 A convenient protocol was developed for the transformation of N-aryl-substituted benzamides to N-aryl-substituted benzothioamides using N-isopropyldithiocarbamate isopropyl ammonium salt as a novel thiating reagent.

Kinetically Stable Boron‐Heteroatom Bonds
Angewandte Chemie, EarlyView.This study investigates the kinetic stability of boron‐heteroatom bonds in N‐methyliminodiacetic acid (MIDA) boronates. The hemilabile nature of the ligand enables the synthesis of molecules that would otherwise be considered too hydrolytically labile. Depending on the structure, acid‐promoted migration of the boryl group was found to produce compounds

N-(Cyanomethyl)benzamide [PDF]
Acta Crystallographica Section E Structure Reports Online, 2010 In the structure of the title compound, C(9)H(8)N(2)O, the amide group is twisted by a dihedral angle of 21.86 (7)° with respect to the benzene ring, while the planes of the benzene ring and cyano-methyl group form a dihedral angle of 53.13 (11)°. In the crystal structure, mol-ecules are linked via N-H⋯O hydrogen bonds, forming a chain running parallel

Antiviral Mechanisms of N-Phenyl Benzamides on Coxsackie Virus A9
Pharmaceutics, 2023 Enteroviruses are one of the most abundant groups of viruses infecting humans, and yet there are no approved antivirals against them. To find effective antiviral compounds against enterovirus B group viruses, an in-house chemical library was screened ...

A Strong Lewis Acidic Diethylsilylium Catalyst for Direct Sulfonamidation of Challenging Ketones
Advanced Science, EarlyView.Low‐substitution‐order silylium ions (R2HSi+) exhibit exceptional Lewis acidic activity. We report diethylsilylium‐catalyzed reductive sulfonamidation of functionalized ketones to access β‐amino esters. The in situ generated ion pair shows enhanced reactivity, with diethylsilane serving as both reductant and precatalyst. The developed protocol proceeds
