Diphenyl phosphorochloridate is a versatile phosphorylation reagent for synthesizing monoalkyl phosphates, α-substituted β-lactams, anhydrides, esters, thioesters, and enol phosphates¹. Its applications span peptide synthesis, aldoxime to nitrile conversion, and the synthesis of glycosyl phosphates in nucleotide sugar production. Additionally, it is valuable in preparing enol and ketene acetal phosphates for metal-catalyzed coupling reactions. The reagent is a moisture-sensitive, viscous, and colorless liquid that should be stored under nitrogen in a cool, dry place.
