A simple multicomponent reaction of aldehydes, diethyl phosphite, and azides gives α-aminophosphonates in the presence of iodine and iron under solvent-free conditions. The reactions were completed at room temperature within 5 minutes to 12 hours and afforded the corresponding products in good yields.
