摘要: Six molybdenum imido alkylidene complexes bearing an N-chelating N-heterocyclic carbene (NHC), i.e., Mo(N-2,6-Me2-C6H3)(CHCMe2Ph)(1-(2-pyridyl)methylene-3-mesitylimidazol-2-ylidene)(OTf)2 (1), Mo(N-2,6-Me2-C6H3)(CHCMe2Ph)(1-(2-pyridyl)methylene-3-mesitylimidazol-2-ylidene)(OTf)(OC6F5) (3), Mo(N-2,6-Me2-C6H3)(CHCMe2Ph)(1-(2-pyridyl)methylene-3-mesitylimidazol-2-ylidene)(OTf)(OCMe3) (4), and their cationic counterparts [Mo(N-2,6-Me2-C6H3)(CHCMe2Ph)(1-(2-pyridyl)methylene-3-mesitylimidazol-2-ylidene)(OTf)]B(ArF)4 (2), [Mo(N-2,6-Me2-C6H3)(CHCMe2Ph)(1-(2-pyridyl)methylene-3-mesitylimidazol-2-ylidene)(OC6F5)]B(ArF)4 (5), [Mo(N-2,6-Me2-C6H3)(CHCMe2Ph)(1-(2-pyridyl)methylene-3-mesitylimidazol-2-ylidene)(OCMe3)]B(ArF)4 (6), have been prepared. The influence of the alkoxide ligand on loss triflate in hexacoordinated 1, 3, 4 resulting corresponding was studied. 2-pyridyl-donor-functionalized NHC renders high oxidation state imi...
