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.
In the presence of a palladium(0) complex catalyst, methoxymethyldisilanes, (MeO)n Me3-nSiSiMe3-m (OMe)m (m, n 1, 2), added to 1-hexyne, trimethylsilyl-acetylene and acetylene to give double silylation products, 1,2-bis(methoxy-methylsilyl)olefins, in varying yields.

The silylenes MeSiCl, MeSiOMe and MeSiNMe2 can be thermally generated from disilanes and trapped by butadiene, isoprene and 2,3-dimethylbutadiene to give functionally-substituted silacyclopentenes. Some examples of cycloadditions to heterodienes are included to demonstrate the scope and mechanism of the reaction. The reactivity of 1-chloro-1-methyl-silacyclopent-3-ene has been studied.
