Abstract: The invention relates to a process for preparing organosilicon group containing photoinitiators of the formula (I), wherein m is a number from 1 to 200; q is 0 or 1; A is IN-C(O)-O-CHR 3 -Y- or IN-C(O)-NH-CHR 3 -Y-; A' is A or R 1 '; R 1 and R 1 ', R 2 and R 2 ' are C 1 -C 18 alkyl or phenyl, or -(O) q -SiR 1 R 1 'R 2 ; R 3 is hydrogen or C 1 -C 6 alkyl, Y is a divalent group selected from C 1 -C 10 alkeylene, C 2 -C 10 alkenylene or -(CH 2 ) b -O-(CH 2 ) a -; and b are each independently of the other a number of 1 to 6; IN is a photolabile functional moiety of the formula (II) or (III), wherein R 4 is hydrogen or -C(O)-C(O)-OH or -C(O)-C(O)-OC 1 -C 6 alkyl and n is 1-3; R 5 and R 6 are C 1 -C 1-2 alkyl or together are cycloC 5 -C 7 alkyl; R 7 is hydroxy, C 1 -C 6 alkoxy or morpholinyl; X is -(CH 2 ) a -, -(CH 2 ) b -O-(CH 2 ) a - or -(CH 2 ) b -O-CO-(CH 2 ) a -; a and b are each independently of the other a number of 1 to 6; whereby the process is characterized in that a photolabile functional moiety containing a carboxy group (IN-COOH) or an alkoxycarbonyl group (IN-CO-OC 1 -C 6 alkyl) is reacted with a carbinol- or amino terminated organosilicon compound of the formula (IV), wherein m, R 1 and R 1 ', R 2 and R 2 ' are as defined above and B is -Y-CHR 3 -OH or -Y-CHR 3 -NH 2 ; B' is B or R 1 ', in the presence of an enzyme which catalyzes the esterification, transesterification or amidation reaction.
