Reactivity of hypervalent silicon and tin compounds toward electrophilic sulfur

Sulfuration of hypervalent complexes of silicon and tin was attempted with several electrophilic sulfur reagents for making carbon-sulfur bonds under almost neutral conditions. We provided a qualitative scale of reactivity be tween various hypervalent salts. Simple and practical methodologies involvi ng non-odorous elemental sulfur were developed. It avoided the use of H2S o r standardized organolithium and Grignard solutions with sulfur, under high ly basic conditions. (C) 2000 Elsevier Science Ltd. All rights reserved.
