Novel .omega.alkenyl silane monoadducts and bis-.alpha., .omega.-silyl alkanes are disclosed. The .omega.-alkenyl silanes or bis-.alpha.,.omega.-silyl alkanes are prepared by the selective addition of silane having chlorine, alkoxy or acyloxy groups to an .alpha.,.omega.-diene. The additions may be carried out in the liquid phase in the presence of free radical and/or metal and/or metal salt catalyst.
