摘要：1. A process for the preparation of alpha-aminoalkylphosphonic and of alpha-aminoalkylphosphinic acids of the formula I see diagramm : EP0184753,P10,F1 where n =1 or 0, R1 = H, CH3 or CH2 -C6 H5 , and R2 = H (for n = 1) and also = alkyl or phenyl (for n= 0), wherein compounds of the formula II see diagramm : EP0184753,P10,F2 where n andR1 have the same meaning as in formula I, R3 = alkyl (for n = 1), alkyl or phenyl (for n = 0),and M**p+ = p-valent cation, are subjected to a Hofmann degradation and thecompounds of the formula I are obtained in the known manner.
