摘要：

The cross-coupling reaction of diethyl- or dimethylzinc compounds with disubstituted vinylic tellurides as electrophilic partners is described. These cross-coupling reactions were catalyzed by Pd(PPh3)(4)/CuI and were shown to by general, allowing the formation of a new sp(3)-sp(2) carbon-carbon bond. Good yields and high stereoselectivity were observed in all cases. (C) 2000 Elsevier Science Ltd. All rights reserved.
