A copper-catalyzedoxidative cross-dehydrogenative coupling (CDC) strategy of secondary phosphine oxides and alcohols for the synthesis of various phosphinate esters was proposed. Under the mild reaction conditions (CuCl2·2H2O/K2S2O8, at room temperature for 3–12 h under air), a variety of substrates were well-tolerated and afforded the desirable compounds in moderate to excellent yields.

The insertion of arynes into P–O bonds for the preparation of o-hydroxy-substituted arylphosphine oxides, -phosphinates, and -phosphonates is described. This novel reaction leads to the simultaneous formation of C–P and C–O bonds in one step with good yields and regioselectivities under mild and transition-metal-free conditions. The easy follow-up transformations of the resulting o-hydroxyl group extend
