摘要：

The efficient cross-coupling reactions of different alkynyl organozinc reagents with unsaturated organotellurium species catalyzed by Pd(PPh3)(4)/CuI and using THF/DMF systems are described. These cross-coupling reactions are general and permit the formation of new sp-sp(2) carbon-carbon bonds. New reactions to reach the necessary alkynylzinc intermediates were also developed from terminal alkynes or using acetylenic tellurides as starting materials. (C) 2000 Elsevier Science Ltd.
