Nickel complexes of phosphine-appended benzannulated boron heterocycles

We report the synthesis and characterization of two diphosphine nickel complexes containing 9-borafluorene (PBFlu, 9-(diisopropylphosphino)phenyl-9-borafluorene) and 9,10-dihydroboranthrene (B2P2, 9,10-bis(2-(diisopropylphosphino)phenyl)-9,10-dihydroboranthrene) cores. Metalation of PBFlu and B2P2 with Ni(PPh3)4 leads to the monometallic complexes (PBFlu)Ni(PPh3) and (B2P2)Ni, respectively. Cyclic voltammetry studies show a reversible redox event at ∼0.1 V and a quasi-reversible event at ca. −3 V versus ferrocene/ferrocenium for (B2P2)Ni while (PBFlu)Ni(PPh3) features no reversible redox events. Electronic structure calculations were performed to provide further insight into the bonding in these complexes.
