ABSTRACT:
The invention relates to a process for preparing N,N'-disubstituted p-quinonediimines of general formula I ##STR1## wherein a corresponding N,N'-disubstituted p-phenylenediamine is oxidized in alkaline/alcoholic solution, and also their use. The invention further provides organosilanes containing methacryloxy or acryloxy groups and having general formula II ##STR2## where R.sup.3 is a hydrogen atom or a methyl group and R.sup.4 and R.sup.5 are identical or different alkyl groups having from 1 to 4 carbon atoms and m is equal to 0 or 1 or 2, which organosilanes contain N,N'-disubstituted p-quinonediimines. Processes for preparing and stabilizing organosilanes of general formula II are described.
