✦ Synopsis

Treatment of chlorobis(methyldiphenylsilyl)methyllithium with vinylic Grignard reagents and CuCN•2LiCl afforded a,a-bis(silyl)-substituted allylic copper species. The reactions of the reagents with electrophiles provided a variety of 1,1-disilylalkenes.

In 1959 Cava reported' that a,a'-dibromo-c-quinodimethane (z), generated by treatment of a,a,a',a'-tetrabromo-o-xylene (1) with NaI in warm DMF, --could be trapped by dienophiles to give 2,3-disubstituted naphthalenes. Cava's scheme is shown below with &phenylmaleimide as the trapping agent.
