Addition of chloromethyl- and methoxymethyldisilanes, X3-mMeMSiSiMenX3-n (X = Cl and OMe; m, n=0-2), as well as hexamethyldisilane, to allene and 1,2-butadiene in the presence of Pd(PPd3)4 catalyst gave regioselectively new functionalized organosilicon compounds, 2,3-bis(organosilyl)prop-1-enes and 2,3-bis(organosilyl)but-1-enes, respectively.Other Group VIII metal-phosphine complexes also affected the reaction, but results were found to be less satisfactory.Also, the reaction of an unsymmetrical disilane with an allenic compound gave only a single product; e.g., the addition of chloropentamethyldisilane to 1,2-butadiene in the presence of Pd(PPh3)4 gave CH2=C(SiMe3)CH(SiMe2Cl)Me in 93percent yield.
