An efficient and general copper(i)-catalyzed method for the synthesis of multi-substituted vinylsilanes is reported.
entry to the corresponding β-silylenamides and -acrylates, which were formed with high levels of regio- and stereoselectivities. A highly efficient catalytic silylcupration of activated alkynes is reported. Upon reaction with silylboronates and methanol in THF at room temperature in the presence of copper(I) fluoride tris(triphenylphosphine), a range of ynamides and propiolates were found to undergo a
