[Constitution] A method for preparing diphenylamine from cyclohexanone and aniline by adding dropwise nitrobenzene and cyclohexanone to a reaction system in which a hydrogen transfer catalyst and a sulfur-free polar solvent are present and aniline is being formed from nitrobenzene as a hydrogen acceptor.
[Effect] Diphenylamine can be obtained in a high yield under moderate reaction conditions.

Attempts at performing dynamic kinetic resolution on a series of cyclic ketimines by making use of an asymmetric organocatalysed hydrosilylation gave modest conversion and moderate to good enantioselectivities. In the case of alpha-tetralone derivatives, the use of an N-benzyl protecting group was found to be crucial in obtaining enhanced levels of selectivity. (C) 2013 Elsevier Ltd. All rights reserved.
