Abstract
WE describe a new, convenient and high yielding procedure for the preparation of diethyl α-aminophosphonates in water by one-pot reaction of aromatic aldehydes, aminophenols and dialkyl phosphites in the presence of a low catalytic amount (10mol%) of citric, malic, tartaric, and oxalic acids as a naturel, recyclable and highly stable catalyst.
