New Molybdenum Imido Alkylidene Complexes that Contain Boron and Their Activity Toward Linear Olefin Homometathesis.

Abstract : A new molybdenum imido alkylidene complex Mo(N(2,6-iPr2C6H3))(CHCMe2Ph)(NC4H2Me2)(OB(Mes)2) 1 (Mes = 2,4,6-MePh) containing both boroxide and pyrrolide ligands is reported. Its formation results from the reaction between bis(mesityl)borinic acid (Mes)2BOH and the bispyrrolide Schrock-type precursor Mo(N2,6-iPr2C6H3)(CHCMe2Ph)(NC4H2Me2)2. The complex was fully characterized by 1H, 13C, 11B and 95Mo NMR spectroscopy and X-ray diffraction. Complex 1 proved to be active for homocoupling metathesis reaction of 1- and 2-octene at 0.1 mol %. The synthesis of mixed pyrrolide boroxide imido molybdenum alkylidene complexes was extented to other borinic acids. The catalytic activity of these new complexes was evaluated in homometathesis of linear olefins.
