摘要：

1-Trialkylsilyl-1-alkynes can be directly coupled with vinyl triflates in the presence of TBAF, 3H(2)O and a catalytic amount of AgI and Pd(PPh3)(4). Functionalized enynes can thus be obtained in good to excellent yields without prior deprotection of the alkyne. (C) 2001 Published by Elsevier Science Ltd.
