tetraallylsilane Production

Tetraallylsilane (1112-66-9) can be prepared from a silicon tetrahalide,such as silicon tetrachloride,and an allyl halide,such as allyl bromide,by the Grignard reaction.For example, allyl bromide can be reacted with magnesium in ether solution to form allyl magnesium bromide.The ether solution of this product is then reacted with silicon tetrachloride,preferably in the mol ratio of at least four mols of the allyl compound to one mol of the silicon compound.
