合成了单齿芳基硅酰胺配体[Ar(Me_3Si)N]_3MoN_2(THF)_2[N(SiMe_3)Ar](5)和[Ar(Me_3Si)N]_3MoN_2SiMe_3(6)(Ar=3,5-Me_2C_6H_3)担载的钼氮配合物,并对其结构进行了表征,证明它们是环己二烯歧化和端烯异构化的有效催化剂。~1H核磁共振谱表明,在催化反应过程中,桥氮配体保持不变,表明Mo-N=N基序可能具有催化能力。
Abstract Molybdenum dinitrogen complexes supported by monodentate arylsilylamido ligand, [Ar(Me3Si)N]3MoN2Mg(THF)2[N(SiMe3)Ar] (5) and [Ar(Me3Si)N]3MoN2SiMe3 (6) (Ar = 3,5-Me2C6H3) were synthesized and structurally characterized, and proved to be effective catalysts for the disproportionation of cyclohexadienes and isomerization of terminal alkenes. The 1H NMR spectrum suggested that the bridging nitrogen ligand remains intact during the catalytic reaction, indicating possible catalytic ability of the Mo-N=N motif.
