Patent ID: 7049454

Claim:
Process for preparing a dialkoxysilacyclohexane of formula in which R 1 and R 2 , which may be identical or different, represent alkyl radicals containing 1 to 5 carbon atoms, and X and Y, which may be identical or different, are alkyl radicals containing 1 to 6 carbon atoms, the method comprising reacting an alkylenedimagnesium dibromide of formula with a tetraalkoxysilane of formula (OR a )(OR b )(OR c )(OR d )Si, in which R a , R b , R c , and R d are selected from the same group as X and Y, at least one of the radicals R a , R b , R c , and R d being identical to X, and at least one of the radicals R a , R b , R c , and R d being identical to Y.
