Abstract

Thiasilacycloalkanes are most commonly prepared by cyclization of (a, w-dihaloalkyl) dialkylsilanes under the action of S-nucleophiles, intramolecular cyclization of (chloroalkyl)( mercaptoalkyl) silanes, or intramolecular free-radical cyclization of (mercaptoalkyl)- alkenylsilanes [1]. In particular, these methods have been used for preparing, in good yields, a rare representative of six-membered heterocycles, 3, 3-dimethyl-3-silathiane [235]. ...
