Abstract
A copper/N-heterocyclic carbene (NHC) catalyzed oxidative vicinal diphosphination of styrenes with diphenyl(trimethylsilyl)phosphine proceeds in the presence of LiOtBu and a pyridine N-oxide/MnO2 combined oxidant to deliver the corresponding 1,2-bis(diphenylphosphino)ethanes (DPPEs) in good yields. The present copper catalysis can provide access to the DPPE-type ligands directly from the relatively simple alkenes.
