A convenientsynthesis of different types of α-aminophosphonates via one-pot solvent-free three component reactions of aldehydes, amines and phosphites catalyzed by bismuth salts has been investigated. Bismuth triflate is found to be the most effective catalyst for this reaction.
One-potthree-componentKabachnik–Fieldssynthesis of α-aminophosphonates with high yields from the reaction between carbonyl compound, primary amine, and substituted phosphite can be carried out in a short period, using H-beta zeolite as a reusable catalyst.
environmentally benign method has been developed for the synthesis of α-aminophosphonates. One-pot, three-component reaction of aldehyds, amines, and trialkylphosphite in the presence of silica-supported sodium hydrogen sulfate (NaHSO4-SiO2) as an inexpensive and reusable catalyst under solvent-free conditions at 80 °C affords the corresponding α-aminophosphonates in good yields and short reaction times.

the synthesis of α-aminophosphonates. A three-componentreaction of an amine, an aldehyde or a ketone and a dialkyl phosphite (Kabachnik–Fieldsreaction) took place in one-pot, under solvent-free conditions to afford the corresponding α-aminophosphonates in high yields and short times. The TiO2 catalyzed α-aminophosphonate synthesis in the present study perhaps represents a true three-component reaction
