Chlorophosphines or thiophosphinic acid chlorides of the general formulae RPCl2, R2 PCl or R2 P(=S)Cl are made from feed materials selected from hydrogen-functional primary or secondary phosphines or secondary phosphine sulfides, where R stands for identical or different, linear or branched, substituted or unsubstituted alkyl radicals having from 1-16 carbon atoms, aryl radicals, aralkyl radicals or alkylaryl radicals having from 6-9 carbon atoms or cycloalkyl radicals having from 5-10 carbon atoms. To this end, the feed materials are reacted with phosphorus pentachloride, or with chlorine gas in the presence of phosphorus trichloride at temperatures within the range -78° to +145° C. It is possible for two radicals R to be linked together by one or two substituted or unsubstituted hydrocarbon chains having from 1-4 carbon atoms.

The disclosure relates to a process for making chlorophosphanes from primary or secondary phosphanes, or phosphinic acid chlorides or thiophosphinic acid chlorides from secondary phosphane oxides or sulfides, wherein the respective starting materials are reacted with hexachloroethane at temperatures of 20° to 180° C. The disclosure also provides as a novel chemical substance an isomeric mixture consisting of 9-Cl-9-phosphabicyclononane [3.3.1] and 9-Cl-9-phosphabicyclononane [4.2.1].
