Abstract

A novel method for the rapid and efficient conversion of a variety of α-aminophosphonates to α-ketophosphonates using ZnCr2O7˙3H2O via oxidative deamination under solvent-free conditions at room temperature is described. This method is also applicable to the rapid and highly selective oxidation of various types of ordinary amines (primary and secondary) to aldehydes and ketones in good to high yields.
