An efficient palladium-catalyzed 2-fluoroallylation of P(O)H compounds with gem-difluorocyclopropanes is presented. The reaction provides a variety of 2-fluoroallylic phosphorus compounds in good yields with high Z selectivity through the sequential C–C bond activation, C–F bond cleavage, and C–P coupling process. Various H-phosphonates, H-phosphinates, and secondary phosphine oxides are all tolerated. In addition, the gram-scale synthesis and the late-stage modification of complex bioactive molecules show practical utilities of the transformation.
