Abstract
The invention provides organosilane compounds of a novel class having one or two (phenyl dimethyl carbinyl) groups bonded to the silicon atom as represented by the general formula (PhMe.sub.2 C).sub.p R.sub.q X.sub.r Si, in which Ph is a phenyl group, Me is a methyl group, R is a monovalent hydrocarbon group selected from the class consisting of alkyl, alkenyl and aryl groups, X is a halogen atom or an alkoxy group, p is 1 or 2, q is zero, 1 or 2 and r is zero, 1, 2 or 3 with the proviso that p+q+r=4. The compound can be prepared by the reaction of a Grignard reagent PhMe.sub.2 C. MgY, in which Y is a halogen atom, with a silane compound represented by the general formula R.sub.q SiX.sub.4-q in an organic solvent.
