✦ Synopsis

A communication on a closely related subject by Hauser and RheeI prompt us to disclose our preliminary results on a simple synthetic method for the transformation of benzene derivatives to naphthslenering systems. This novel method' is based on the reaction of ortho-substituted benzyl sulfones (A) with Michael acceptors, followed by elimination of water and p-toluenesulfinic acid (TosH), e.g. Scheme 1.
