PCT No. PCT/EP92/02215 Sec. 371 Date Feb. 3, 1994 Sec. 102(e) Date Feb. 3, 1994 PCT Filed Sep. 24, 1992 PCT Pub. No. WO93/08228 PCT Pub. Date Apr. 29, 1993.The invention relates to a process by which organosilicon compounds carrying sulfur-containing organic radicals can easily be prepared by reacting organosilicons of the general formula Ra(R1O)bR2cSiO(4-a-b-c)/2(I) in which R can be identical or different and is a monovalent organic radical, R1 can be identical or different and is a hydrogen atom or a monovalent organic radical, R2 can be identical or different and is a radical -QX, where Q is a divalent hydrocarbon radical and X is a halogen atom, a is 0, 1, 2 or 3, b is 0, 1, 2 or 3 and c is 0, 1, 2 or 3, with the proviso that the organosilicon compound has at least one radical R2 per molecule and the sum of a, b and c is less than or equal to 4, with sulfite in the presence of water.
