hydrogenchloride in pentane Under stirring a strong stream of hydrogenhalogenide is bubbled for 3-10 min through the cooled (-50-0°C) soln. of phosphine complex (inert atmosphere).; Solvent is evapd. at room temp. in vac., residue is digested with pentane, dialkylamminhydrohalogenide is filtered off, filtrate is dried to dryness in vac., recrystn. from pentane (-78°C), not purely isolated.;
