Abstract

Attempted reactions of imines which contain a-hydrogens with Grignard reagents generally fail to give acceptable yields of secondary amines by simple addition because of the poor electrophilicity of the imine carbon and competing loss of the a-pr~ ton. l-~ Some organolithiums do add to certain types of imines, but the yields are generally low for the same reason^.^-^ To circumvent these problems, a number of methods have been ...
