  Coordination chemistry of molybdenum relevant to hydrodenitrogenation: Reactivity of Mo(PMe3)6 towards 6-membered heterocyclic aromatic nitrogen compounds involving C–H bond cleavage and η6-coordination

  摘要：

  The reactivity of Mo(PMe(3))(6) towards 6-membered heterocyclic aromatic nitrogen compounds, namely pyridine, pyrazine, pyrimidine and triazine, has been investigated as part of an effort to define the coordination chemistry of molybdenum relevant to hydrodenitrogenation. For example, Mo(PMe(3))(6) reacts with pyridine to yield initially (eta(2)-N,C-pyridyl)Mo(PMe(3))(4)H, an uncommon example of an eta(2)-pyridyl-hydride complex. The formation of (eta(2)-N,C-pyridyl)Mo(PMe(3))(4)H is reversible and treatment with PMe(3) regenerates Mo(PMe(3))(6) and pyridine. At elevated temperatures, (eta(2)-N,C-pyridyl)Mo(PMe(3))(4)H dissociates PMe(3) and converts to the eta(6)-pyridine complex (eta(6)-pyridine) Mo(PMe(3))(3). Pyrazine, pyrimidine and 1,3,5-triazine likewise react with Mo(PMe(3))(6) to yield (eta(2)-N,C-pyrazinyl)Mo(PMe(3))(4)H, (eta(2)-N,C-pyrimidinyl)Mo(PMe(3))(4)H and (eta(2)-N,C-triazinyl)Mo(PMe(3))(4)H, respectively. At elevated temperatures (eta(2)-N,C-pyrazinyl) Mo(PMe(3))(4)H and (eta(2)-N,C-pyrimidinyl) Mo(PMe(3))(4)H dissociate PMe(3) and convert to (eta(6)-pyrazine)Mo(PMe(3))(3) and (eta(6)-pyrimidine) Mo(PMe(3))(3) in which the heterocycle coordinates to molybdenum in an unprecedented eta(6)-manner.
