Process for making chlorophosphines and thiophosphinic acid chlorides, and 9-chloro-9-thioxo-9-phosphabicyclononanes

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.
