Zusammenfassung:INNER AMMONIUM SALTS OF PHOSPHINIC ACIDS Zwitterionic compounds of the formulae and wherein R, R1, R2 and R3 each represent hydrogen or simple aliphatic hydrocarbon radicals, R4 alkyl,cycloalkyl or aralkyl groups having up to 15 carbon atoms and R5 bivalent alkylene, cycloalkylene or aralkylene radicals having up to 25 carbon atoms as well as a process for preparing such compounds by reacting 2-oxo-2-alkyl-1.2-oxaphospolanes with primary or secondary , monovalent or bivalent amines.
