Allylation of chlorosilanes has been achieved with allylsamarium bromide, especially in a controlled manner. Thus allylation of trisubstituted chlorosilanes (R3SiCl) afforded a variety of aryl, aralkyl, and alkenyl substituted allylsilanes. Dichlorosilanes (R2SiCl2) can either afford monoallylated silanes or diallylated silanes depending on the amount of allylsamarium bromide used. Similarly, trichlorosilanes (RSiCl3) can selectively afford mono-, di-, and tri-allylation products. Finally, perchlorosilane (SiCl4) was allylated stepwise and the corresponding silanes containing one, two, three or four allylic groups, respectively, were obtained in satisfactory yields.
Process for preparing organochlorosilanes by dehydrohalogenative coupling reaction of alkyl halides with chlorosilanes

The present invention relates to a process for preparing organochlorosilanes and more particularly, to the process for preparing organochlorosilanes of R4R3CHSiR1Cl2(I) by a dehydrohalogenative coupling of hydrochlorosilanes of HSiR1Cl2(II) with organic halides of R2R3CHX (III) in the presence of quaternary phosphonium salt as a catalyst to provide better economical matter and yield compared with conventional methods, because only a catalytic amount of phosphonium chloride is required and the catalyst can be separated from the reaction mixture and recycled easily.
