Organosilicon compounds (P) containing .alpha.,.beta.-unsaturated carboxylic acid radicals, of the general formula (1) -A-O-C(O)-CR=CH2 (1), are prepared by a process in which, in a first step, organosilicon compounds (H) containing hydrogen atoms bonded directly to silicon are reacted with olefinically unsaturated compounds (U) containing a terminal double or triple bond, of the general formula (2) .OMEGA.-O-C(O)-CRH-CH2-Z (2), in the presence of metals or compounds from the platinum group as catalyst, to give organosilicon compounds (E) containing radicals of the general formula (3) -A-O-C(O)-CRH-CH2-Z (3), and, in a second step, H-Z compounds are eliminated from organosilicon compounds (E), where A is a divalent organic radical, .OMEGA. is a monovalent organic radical containing a terminal double or triple bond, R is an H atom or a methyl radical, and Z is Cl, I, Br or 4-methyltoluenesulfonyl.
