An efficient and stereoselective procedure for the preparation of E-1-alkenylphosphonates by copper-mediated cross-coupling between 1,1-dibromo-1-alkenes and dialkyl phosphites is reported. The reaction allows for formal substitution of both bromine atoms, respectively, by an hydrogen and a dialkoxyphosphoryl.
