Abstract
Disubstituted aminotriphenylphosphonium bromides were obtained in excellent yields from the reaction of triphenylphosphine dibromide and the secondary amines using simple procedures. This method has an advantage in the preparation of cyclic aminophosphonium salts, such as those of morpholine or piperidine. The treatment of the disubstituted aminophosphonium salt with bases resulted in dehydrohalogenation, followed by a Hofmann-like decomposition, and gave imine and triphenylphosphine.
