The dehydration reaction of primary amides is one of the most fundamental methods for the synthesis of nitriles, and the development of environmentallybenign catalytic reaction processes is needed. We surveyed a variety of metal catalysts and found that perrhenic acid was extremely effective for the dehydration of not only primary amides but also aldoximes. Typically, 1 mol % of perrhenic acid gave
N-Acylation of dithieno[3,2-b:2′,3′-d]pyrrole (DTP) leads to enhanced open-circuit voltages and hence higher power conversion efficiencies in polymer solar cells.

Highly Selective Ruthenium-Catalyzed Direct Oxygenation of Amines to Amides
Reports on aerobic oxidation of amines to amides are rare, and those reported suffer from several limitations like poor yield or selectivity and make use of pure oxygen under elevated pressure. Herein, we report a practical and an efficient ruthenium‐catalyzed synthetic protocol that enables selective oxidation of a broad range of primary aliphatic, heterocyclic and benzylic amines to their corresponding
