Stoichiometric reactivity of complexes 1 and 2 with nitriles and HBCat suggest that catalytic reactions proceed via a series of agostic borylamido and borylamino complexes. For complex 1, catalysis starts with addition of nitriles across the Mo–H bond to give (ArN)Mo(Cl)(NvCHR)(PMe3)2; whereas for complex 2 stoichiometric reactions suggest initial addition of HBCat to form the agostic complex Mo(H)2(PMe3)3(η3-NAr-HBcat)enAttribution-NonCommercial-ShareAlike 3.0 United StatesResearch Subject Categories::NATURAL SCIENCES::ChemistryImido–hydrido complexes of Mo(IV)Article
