The first direct coupling of 1-trialkylsilyl-1-alkynes with vinyl triflates; a new access to enynes

1-Trialkylsilyl-1-alkynes can be directly coupled with vinyl triflates in the presence of TBAF, 3H2O 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.
