    • Synthesis, structure, and reactivity of terminal cobalt imido complexes
    Authors: Shay, Daniel Travis (2006)

    The synthesis and structural characterization of imido ligated cobalt complexes that employ the sterically hindered hydrotris(3-`Bu-5-Me-pyrazolyl)borate ligand, i. e., TptBu,MeCoNR (R = Me, Et, `Bu, Ad) have been accomplished. These terminal imido complexes possess relatively short Co-N bond distances in the range of 1.64-1.67 A, indicating a multiple bond to the metal. Reactivity studies have been undertaken with a variety of substrate ranging from protonation using acids such as HC1 and lutidinium-BARF (BARF = tetrakis(3,5-bis(trifluoromethyl)phenyl)borate) to ligand transfer of the imido fragment to carbon monoxide. Kinetic studies of the thermal decomposition of Tp'Bu,MeCoN...
