An unprecedented method for the transformation of 2-substituted acrylates into β-ketophosphine oxides has successfully been developed via hydrochloric acid-promoted copper/iron-cocatalyzed deesterificative oxyphosphorylation under dioxygen atmosphere, simultaneously inhibiting the formation of the preceding hydroxyphosphorylation products. Through this convenient and practical process, a library of structurally diverse β-ketophosphine oxides could be selectively and effectively obtained with broad substrate scope and good functional group tolerance under mild conditions, accompanied by chemoselective cleavage of C(sp2)-C(C=O) bonds.

Key words: β-ketophosphine oxides, 2-substituted acrylates, hydrochloric acid, copper/iron-cocatalysis, dioxygen
