Hydrophosphonylation of Benzoylhydrazones Using Iodine as a Catalyst: A Facile Synthesis of alpha-(N '-Acylhydrazino)-Substituted Phosphonates

[摘要]：A simple and efficient method for the synthesis of alpha-(N'-acylhydrazino)-substituted phosphonates has been developed using the hydrophosphonylation of benzoylhydrazones with triethyl phosphite in the presence of iodine as a catalyst at room temperature. The products are formed in excellent yields (89-95%) within two to three hours.
