Mechanism of addition of silanediyls (silylenes) to buta-1,3-diene
Abstract
From experiments on the addition of :SiMeX (X = H, Cl, Me) to Buta-1,3-diene, it is concluded that the main cyclic adduct in each case results from initial 1,2-addition to form a vinylsilacyclopropane followed by a 1,3-silyl shift, rather than Si–C bond rupture.
