alkynes and diynes with Me3SiI with the aid of NEt(i-Pr)2 occurs smoothly, leading to the formation of mono- and bis-silyl-functionalized alkynyl derivatives. This new reaction, which occurs via direct activation of the Csp−H bond in the starting alkyne, is a very efficient and easy tool for the synthesis of unique silylated alkynes.
