Abstract: A combination of ultrasonic (US) and [bmim]AlCl₄ ionic liquid is used as an alternative to conventional acid catalysts in the Kabachnik-Fields reaction of an amine and aryl aldehyde with phosphite leading to the formation of aminophosphonates. The reaction time was significantly reduced and the reaction progressed very smoothly.

Keywords: ionic liquid – ultrasound – aminophosphonate – Kabachnik-Fields reaction – multi-component reaction
