Description and Uses

Diphenyl chlorophosphate is used to prepare cyclohexyl-amidophosphoric acid diphenyl ester by reacting with cyclohexylamine. It is also used in the synthesis of alfa-substituted beta-lactams, anhydrides, esters and thioesters. It is also employed in the conversion of aldoximes to nitriles. Further, it is used in the preparation and reaction of enol phosphates, guanosine-adenosine-5',5'-triphosphate, guanosine-cytidine-5',5'-triphosphate, guanosine-uridine-5',5'-triphosphate, diguanosine-5',5'-diphosphate and diguanosine-5',5'-triphosphate. In addition to this, it serves as a phosphorylating agent for the preparation of 2-deoxy-D-galactose-3 and -6 phosphoric acids.
