摘要： Organosilicon compounds (P) containing &agr;,&bgr;-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) &OHgr;—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, &OHgr; 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.
