LiI/TBHP Mediated Oxidative Cross-Coupling of P(O)-H Compounds with Phenols and Various Nucleophiles: Direct Access to the Synthesis of Organophosphates
Direct phosphorylation of P(O)–H compounds with various nucleophiles such as phenols, alcohols, amines and enols is described using oxidative cross‐coupling strategy. The phosphorylation of hydroxylated naphthyls and heteroarenes has been achieved. Main features of this transformation are short reaction time, functional group tolerance, and broad substrate scope.

We report a diaryldiselenide catalyst for cross-dehydrogenative nucleophilic functionalization of hydrophosphoryl compounds. The proposed organocatalytic cycle closely resembles the mechanism of the Atherton–Todd reaction, with the catalyst serving as a recyclable analogue of the halogenating agent employed in the named reaction. Phosphorus and selenium NMR studies reveal the existence of a P–Se bond
