Abstract

Abstract Mediated by low-valent titanium, generated from TiCl 3/LiAl 4. ammonia is incorporated into benzophenone to give N-(diphenylmethylene)-N-(diphenylmethyl) amine in a synthetically useful reaction. A good yield (65%) requires that the temperatures of the reaction stages are well controled and that ammonia and ketone are simultaneously introduced keeping their molar ration 1: 1. The possible sequence of reactions is ...
