Zirconium(IV) compounds are reported as excellent catalysts for a three-component one-pot reaction of an amine, an aldehyde or a ketone, and a di/trialkyl/aryl phosphite to form α-aminophosphonates under solvent-free conditions at rt. Among the various zirconiumcompounds, ZrOCl2·8H2O and ZrO(ClO4)2·6H2O were most effective. The reactions were faster with dialkyl/diaryl phosphites than with trialkyl/triaryl

Abstract An ultrasound-assisted simple, easy and straightforward method for the synthesis of α-aminophosphonates has been developed via Kornblum/Kabachnik-fieldsreaction. The method involves in situ generation of an aldehyde intermediate from benzyl halides via oxidative dehalogenation followed by coupling with aryl amine and trialkyl phosphite in a one-pot three component manner under ultrasonic
