Abstract: The invention relates to a process for the manufacture of organomonosilanes, in particular, bearing both hydrogen and chlorine substituents at the silicon atom by subjecting a silane substrate comprising one or more organomonosilanes, with the proviso that at least one of these silanes has at least one chlorine substituent at the silicon atom, to the reaction with one or more metal hydrides selected from the group of an alkali metal hydride and an alkaline earth metal hydride in the presence of one or more compounds (C) acting as a redistribution catalyst.
