A copper-catalyzed radical Csp3–H/P(OR)3 cross-coupling reaction for the formation of Csp3–P bonds is described. A range of 1,3-dicarbonyl compounds and trialkylphosphites were coupled in this fashion to give the corresponding products in moderate to good yields. This protocol provides direct access to α-phosphonyl 1,3-dicarbonyl compounds.
