    摘要： 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—CHR3—Y— or IN—C(O)—NH—CHR3—Y—; A′ is A or R1′; R1 and R1′, R2 and R2′ are C1-C18alkyl or phenyl, or —(O)q—SiR1R1′R2; R3 is hydrogen or C1-C6alkyl, Y is a divalent group selected from C1-C10alkeylene, C2-C10alkenylene or —(CH2)b—O—(CH2)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 R4 is hydrogen or —C(O)—C(O)—OH or —C(O)—C(O)—OC1-C6alkyl and n is 1-3; R5 and R6 are C1-C1-2alkyl or together are cycloC5-C7alkyl; R7 is hydroxy, C1-C6alkoxy or morpholinyl; X is —(CH2)a—, —(CH2)b—O—(CH2)a— or —(CH2)b—O—CO—(CH2)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—OC1-C6alkyl) is reacted with a carbinol- or amino terminated organosilicon compound of the formula (IV), wherein m, R1 and R1′, R2 and R2′ are as defined above and B is —Y—CHR3—OH or —Y—CHR3—NH2; B′ is B or R1′, in the presence of an enzyme which catalyzes the esterification, transesterification or amidation reaction.

    摘要： The invention relates to a novel process for the preparation of N-substituted pyrroles, especially of formula (V), wherein the radicals are as defined in the description, by intermolecular aza-Wittig reaction starting from organic azides and 1,4-dioxo compounds. The invention relates also to novel iminophosphorane intermediates for this synthesis. The resulting pyrroles are useful, for example, in the organic synthesis of pharmaceuticals or other active substances and chemicals.
