difunctionalization of alkenes with H-phosphine oxides and dioxygen for the synthesis of β-ketophosphine oxides has been developed undermildconditions. The present protocol, which utilizes an inexpensive catalyst, readily available materials, and environmentally benign oxygen source, provides a convenient and cost-effective approach to construct various β-ketophosphine oxides.

Copper-catalyzed direct oxyphosphorylation of alkynes with H-phosphine oxides and dioxygen: A convenient approach to <font>β</font>-ketophosphine oxides
and facile copper-catalyzed synthesis of β-ketophosphine oxides via direct oxyphosphorylation of alkynes with H-phosphine oxides and dioxygen has been developed under mild conditions without any base or cocatalyst. A radical reaction pathway for the formation of β-ketophosphine oxides is proposed. An 18O labeling experiment suggested that the carbonyl oxygen atom of β-ketophosphine oxides originated
