Abstract
A novel organosilicon compound is disclosed which is an isocyanato group-containing organosilane compound having one or two isopropenyloxy groups as represented by the general formula (CH.sub.2 .dbd.CCH.sub.3 --O).sub.n (CH.sub.3).sub.3-n Si(CH.sub.2).sub.3 NCO, in which n is 1 or 2. The compound can be prepared by heating a mixture of a chlorosilane of the formula (Cl).sub.n (CH.sub.3).sub.3-n Si(CH.sub.2).sub.3 NCO and acetone in the presence of a tertiary amine compound, e.g., triethyl amine, acting as an acceptor of hydrogen chloride and as a catalyst to effect the enolation reaction.
