Abstract: A number of aryl/heteroaryl aminomethylene bisphosphonates were synthesized by one-pot reaction of diverse aryl/heteroaryl amines with diethyl phosphite and triethyl orthoformate in the presence of I2 under solvent free conditions. The product yields are 96%~99%. When the molar fraction of I2 is 5%, the product yield is the highest. The procedure is simple and the substrate scope is large. I2 is safe and very efficient as the catalyst.

Key words: aryl/heteroaryl aminomethylene bisphosphonates, I2, one-pot synthesis, solvent free
