Regioselective O/C phosphorylation of α-chloroketones: A general method for the synthesis of enol phosphates and β-ketophosphonates: Via Perkow/Arbuzov reaction

Abstract

A regioselective O/C phosphorylation of α-chloroketones with trialkyl phosphites was performed for the first time, which employed solvent-free Perkow reaction and NaI-assisted Arbuzov reaction under mild conditions respectively. Versatile enol phosphates were prepared in good to excellent yields as well as β-ketophosphinates.
