The invention provides a novel class of organosilicon compounds which are hydrogenalkenyloxysilanes represented by the general formula <IMAGE> in which R1 is a monovalent hydrocarbon group having from 1 to 8 carbon atoms, R2, R3 and R4 are each a hydrogen atom or a monovalent hydrocarbon group having from 1 to 8 carbon atoms and n is a number of zero, 1 or 2. The silane compounds are readily obtained by the dehydrochlorination reaction between a corresponding hydrogen-containing chlorosilane compound and an alpha , beta -unsaturated aldehyde compound or a ketone compound in the presence of an acid acceptor. The compounds are useful as a modifying agent in the silicone technology and also serve as a curing agent. |
