A modular Cu/ABNO catalystsystem has been identified that enables efficient aerobic oxidative coupling of alcohols and amines to amides. All four permutations of benzylic/aliphatic alcohols and primary/secondary amines are viable in this reaction, enabling broad access to secondary and tertiary amides. The reactions exhibit excellent functional group compatibility and are complete within 30 min-3

The effect of amines, imines and heterocycle compounds on conversion has been studied in transferhydrogenation of camphor and 2-PrOH catalyzed by Raney® nickel. Small amount (5 mol% to nickel) of N-containing compound significantly decreases catalyst activity. It has been shown that the poisoning effect mostly depends on molecular size of amines and heterocyclic compounds. For aniline and cyclohexylamine

A facile procedure for the preparation of secondary and tertiary amines from nitriles has been developed. The addition of amines to diisobutylaluminum-imine complexes derived by treating nitriles with DIBAL-H was found to proceed in moderate to good yields and was used to prepare NPS R-568 (1) hydrochloride, a potent calcium receptor agonist.
