A facile method for the preparation of both 2-pyrrolidinyl-substituted phosphinic acids and 1-aminoalkylphosphinic acids is described. Reaction of 1-pyrroline trimer or N-tritylalkanamine with bis(trimethylsilyl)phosphonite, followed by silylation with N,O-bis(trimethylsilyl)acetamide gives an intermediate which is used in a Michael addition reaction or an Arbuzov reaction.
