A process for the preparation of organopolysilanes which comprises reacting at least one disilane of the general formula RkR3mSi2(OR1)6-k-m (I) in which the radicals R may be the same or different and are hydrogen atoms or monovalent, saturated organic radicals, the radicals R3 may be the same or different and are monovalent, unsaturated organic radicals, the radicals R1 may be the same or different and are monovalent alkyl groups, k is 0, 1, 2 or 3, and m is 1, 2, 3 or 4, in which the sum of k and m is less than or equal to 4, and optionally mixed with a disilane of the formula RnSi2(OR1)6-n (II) in which R and R1 are the same as above and n is 0, 1, 2 or 3, in the presence of at least one compound of the general formula MOR2 (III) in which R2 is a monovalent hydrocarbon radical and M is an alkali metal atom. |
