One-pot synthesis of dialkyl arylaminomethyl- and (arylamino)arylmethylphosphonates and their N-acylated derivatives

A convenient synthesis of dialkyl arylaminomethyl- and (arylamino)arylmethylphosphonates and their N-acylated derivatives have been developed, starting from azomethines and phosphorus trichloride in the presence of an alcohol
