Na2CaP2O7 a new catalyst for the synthesis of α-amino phosphonates under solvent-free conditions at room temperature

Abstract

The synthetic diphosphate Na 2 CaP 2 O 7 was found to be an efficient reagent for the synthesis of α-amino phophonates from imines and dialkyl phosphites. The addition the dialkyl phosphite was carried out under mild conditions at room temperature without solvent. The catalyst was very stable and could be reused several times with high catalytic activity. .
