Novel, alkenyloxy-functional organosilicon compounds are described which contain at least one Si-bonded Y radical per molecule having the formula -(CH2)2-R2-(A-R3)z-O-CH=CR-CH2-R4 (I) , in which A represents -O-, -S- or , R2 represents a linear or branched alkylene radical having from 1 to 7 carbon atom(s) per radical or a cycloalkylene radical having from 5 to 7 carbon atoms per radical, R3 represents a linear or branched alkylene radical having from 2 to 4 carbon atoms per radical, which may be substituted by a hydroxyl group, methoxy group, ethoxy group or trimethylsiloxy group, R4 represents a hydrogen atom or an alkyl radical having from 1 to 4 carbon atom(s) per radical, and z is 0, 1 or 2. The alkenyloxy-functional organosilicon compounds are preferably silanes or organopolysiloxanes. The alkenyloxy-functional organopolysiloxanes can be crosslinked, for example, with ultraviolet light. These organopolysiloxanes can also be used for preparing coatings.
