Abstract

We report on the insertion of electron deficient alkyne, dimethyl acetylene dicarboxylate (DMAD), into the E-Si bond of hypersilyl tetrylenes, PhC(NBu)ESi(SiMe) (E = Ge and Sn), at room temperature. Uniquely, the germylene leads to alkenes, while the stannylene gives access to alkenes, and the insight into divergent stereoselectivity has been obtained by DFT studies.
