Abstract

The first step in the reaction of trimethylsilylmethylene-dimethylsulfurane 1 (prepared from (CH3) 3SiCH2S̄ (CH3) 2Ī with 1 equivalent (CH3) 3COK) with carbonyl compounds (R1)(R2) CHCOCH2R32 leads Peterson-like way to the non-isolable vinylsulfoniumdimethylsilanolate-intermediate B or its recombined product A. Depending on the reaction conditions and the nature of the substituents R1, R2 and R3 there exist five ...
