N-(Trifluoracetyl)succinimide, easily prepared from trifluoroacetic anhydride and succinimide forms a novel, convenient trifluoracetylating reagent. It trifluoroacetylates alcohols, phenols and amines, to generate trifluoroacetate esters, and trifluoracetamides in excellent yields with very efficient work up procedures.

Trifluoromethyl‐containing compounds play a significant role in medicinal chemistry, materials and fine chemistry. Although direct C−H trifluoromethylation has been achieved on Csp2−H bonds, direct conversion of Csp3−H bonds to Csp3−CF3 remains challenging. We report herein an efficient protocol for the selective trifluoromethylation of benzylic C−H bonds. This process is mediated by a combination
The first example of hydrogenation of amides homogeneously catalyzed by an earth-abundant metal complex is reported. The reaction is catalyzed by iron PNP pincer complexes. A wide range of secondary...
