Double silylation of allene and buta-1,2-diene: formation of new organosilicon compounds containing both vinylsilane and allylsilane units
Abstract
Addition of chloromethyl-and methoxymethyl-disilanes, as well as hexamethyldisilane, to allene and buta-1,2-diene in the presence of a Pd (PPh3)4 catalyst gave, regioselectively, new functionalized organosilicon compounds, 2,3-bis(organosily)prop-1-enes and 2,3-bis-(organosilyl)but-1-enes, respectively.
