Abstract

The mechanism of the cyclization of o-benzylbenzophenones is pictured by Bradsher and Vingiello4 as proceeding through the following steps:(1) the reversible addition of a proton to the carbonyl oxygen;(2) reaction between the positive central carbon atom and the ortho position of the benzene ring into which cyclization is to occur;
