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.

participate in 1,4-addition reactions with alpha, beta-unsaturated esters, thiol esters, imides, and nitriles in poor to excellent yields depending upon the electron-withdrawing substituent and the substitution pattern of the unsaturated substrate. These reagents also undergo conjugate addition reactions with alpha,beta-alkynyl esters, sulfoxides, and nitriles and with alpha,beta-beta,gamma-unsaturated allenyl

(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.
