Abstract

[Figure not available: see fulltext.] Air-stable and crystalline tetraaminophosphonium tetrafluoroborates possessing chiral, enantiomerically pure 1,2-diamine moiety have been synthesized by a three-step sequential one-pot approach. The tetrafluoroborate salts can be purified by recrystallization or chromatography and subsequently converted to the phosphazene bases by treatment with t-BuOK. Basicity values in tetrahydrofuran have been measured for the obtained phosphazene bases by means of spectrophotometric titration.
