title: First anionic silyl migration from sp2 carbon to carbonyl oxygen. Stereospecific allylation of (Z)-beta-trimethylsilyl-alpha,beta-unsaturated ketones.
abstract: 1,4-Silyl migration from sp2 carbon to carbonyl oxygen proceeded by the treatment of (Z)-beta-trimethylsilyl-alpha,beta-unsaturated ketones with copper(I) tert-alkoxide to afford vinylmetal species, which reacted with allylic halides to produce enol trimethylsilyl ethers of beta-alk-2-enyl-alpha,beta-unsaturated ketones with complete retention of configuration.
