A catalytic method to access secondary alcs. by the coupling of aryl iodides was reported. Either aldehydes or alcs. can be used as reaction partners, making the transformation reductive or redox-neutral, resp. The reaction was mediated by a Ni catalyst and a 1,5-diaza-3,7-diphosphacyclooctane. This P2N2 ligand, which was previously been unrecognized in cross-coupling and related reactions, was found to avoid deleterious aryl halide reduction pathways that dominate with more traditional phosphines and NHCs. An interrupted carbonyl-Heck type mechanism was proposed to be operative, with a key 1,2-insertion step forging the new C-C bond and forming a nickel alkoxide that may be turned over by an alc. reductant. The same catalyst was also found to enable synthesis of ketone products from either aldehydes or alcs., demonstrating control over the oxidation state of both the starting materials and products.
