Some acyclicacidicionicliquids were prepared and used as the catalysts for the one-pot, three-component synthesis of α-aminophosphonates from aldehydes, amines, and trimethylphosphite at room temperature in water. The products could simply be separated from the system of catalyst/water, and the catalysts could be reused at least six times without noticeably decreasing the catalytic activity.

A sulfonicacidfunctionalized ionic liquid is used as a Brønsted acidcatalyst for the one-pot, three-component synthesis of α-aminophosphonates from aldehydes and ketones at room temperature in water. This homogeneous catalytic procedure is simple and efficient and the catalyst can be reused at least six times without any noticeable decrease in catalytic activity.
