Claims16
A process for preparing organopolysilanes, which comprises reacting an organosilicon compound containing an Si--Si bond and having the general formula ##STR4## where R.sup.1, R.sup.3, R.sup.4 and R.sup.5 are each selected from the group consisting of hydrogen, an alkyl, alkenyl, aryl and alkoxy radical, R.sup.2 is selected from the group consisting of hydrogen and an alkyl radical, x is in the range of from 0.1 to 0.9, y is in the range of from 0.01 to 0.5, z is in the range of from 0 to 0.5 n is in the range of from 2 to 1,000, with the proviso that the sum of (x+y+z) is 1, with boric acid.
