Abstract
Reduction of substituted benzophenones 1 with sodium borohydride and triflu oro-acetic acid yields diphenylmethanes 3 as well as dimers 5 and 6. The co mplete structure of these substituted diphenylmethane dimers 5 may be accur ately determined by H-1, C-13, 2D NMR analysis, and a mechanism for their f ormation is suggested.
