ALKENE CARBOSULPHENYLATION AND CARBOSELENYLATION: THE USE OF ALLYLTRIMETHYLSILANE AND O-SILYLATED ENOLATES.

Alexander, Rikki P.,Paterson, Ian

, p. 5911 - 5914 (2007/10/02)

Allyltrimethylsilane, as well as O-silylated enolates, can be alkylated by the PhSCl adducts of alkenes and vinyl ethers (1, X=SPh); the PhSeCl analogues (1, X=SePh), however, are less useful for alkylation purposes due to competing nucleophilic attack at selenium.
