An iridium methyl complex, [Cp*Ir(bpy)(CH3)]+, was prepared by electrophilic methylation of Cp*Ir(bpy) with CH3I and characterized electrochemically, photophysically, crystallographically, and computationally. Irradiation of the MLCT transition of [Cp*Ir(bpy)(CH3)]+ in the presence of CH3I in acetonitrile produces ethane, methane, propionitrile, and succinonitrile. A series of mechanistic studies indicates
铱甲基配合物[Cp * Ir(bpy)(CH 3)] +通过Cp * Ir(bpy)与CH 3 I的亲电甲基化反应制备,并进行电化学,光学,结晶和计算表征。在乙腈中存在CH 3 I的情况下,对[Cp * Ir(bpy)(CH 3)] +的MLCT跃迁进行辐照会产生乙烷,甲烷,丙腈和丁二腈。一系列的机理研究表明,CC键的形成是由Ir-CH 3键的单金属光化学均质分解产生的游离甲基所介导的。
