  Homogeneous Model Complexes for Supported Rhenia Metathesis Catalysts

  摘要：

  A series of rhenium trioxo complexes (L-ReO3) was synthesized, characterized, and demonstrated to be active in olefin metathesis. The relationship between perrhenate (ReO4-), perrhenyl (ReO3+), and metathesis-active rhenium complexes (L-ReO3) was elucidated. Their chemical behavior can be tuned through the Lewis acid-base interaction. DFT calculations were performed for the metathesis reaction of L-ReO3 with norbornene, which demonstrates that electron-withdrawing substituents or ligands are beneficial for olefin metathesis activity. Moreover, a rhenium-alkylidene complex was synthesized, which can be activated by B(C6F5)(3) to afford an active metathesis catalyst. This be regarded as a homogeneous model of the hypothetical species present in the heterogeneous catalytic systems. The findings from the present study are consistent with our previous gas-phase studies and constitute the elucidation of the working principles for the metathesis-active rhenium species on the surface.
