- Alkylamino-and cycloalkylaminotriphenylphosphonium halides react with elemental halogens or interhalogen compounds to afford alkylamino-or cycloalkylaminotriphenyl-phosphonium trihalides. The stability of these trihalides depends on the cation as well as the trihalide anion. The assignment of a trihalide structure to these compounds was based on elemental analysis and on IR-and Raman spectroscopic evidence. Most stable are the tribromide and [IX₂]⊖ salts. During all reactions involving N-alkylamino-and N-cyclo-alkylaminotriphenylphosphonium halides and elemental halogens an N-halogenation of the cation was not observed.
