摘要:
Acetylenic sulfides are readily oxidized to acetylenic sulfoxides by a solution of pyridine, water, benzoic acid and trichloroisocyanuric acid in acetonitrile and methylene chloride.

Z-beta-sulfonyl alpha,beta-unsaturated ketones, and Z-beta-alkynyl vinyl sulfones. Although the reaction mechanisms are still not clear, the neighboringgroupparticipation of the sulfinyl or sulfonyl group may be playing an important role in this unique hydrozirconation reaction.

(Z)-beta-Organotellurovinyl sulfoxides were synthesized via a highly regio- and stereoselective anti-hydrotelluration of acetylenic sulfoxides. alpha-Organotellurovinyl sulfoxides were obtained from a three component syn-carbotelluration reaction of acetylenic sulfoxides, that is, syn-addition of monoorganocopper reagents to acetylenic sulfoxides followed by the electrophilic reaction of the vinyl copper intermediates with benzenetellurenyl iodide at low temperature. Synthetic applications of the organotellurovinyl sulfoxides have been investigated. (C) 2004 Elsevier Ltd. All rights reserved.

cis-Carbocuperation reaction of monoorganocopper reagent with acetylenic sulfoxides, followed by electrophilic reaction with a variety of electrophiles, provided a regio- and stereoselective method to prepare the versatile polysubstituted vinyl sulfoxides. Sonogashira cross-coupling reaction of the obtained alpha-iodovinyl sulfoxides with terminal acetylenes was also investigated to afford the versatile conjugate sulfinyl enynes. (C) 2004 Elsevier Ltd.
