利用CoMe(PMe3)4或者CoMe3(PMe3)3与[PCP]-钳式配体,[Ph2P(ortho-C6H4)]2CH2(1),室温下反应,在实现碳氢键活化的同时,合成了钴的钳式配合物[PCP]Co(I)(PMe3)(2).配合物2与卤代烃C6Cl6, EtBr, n-BuBr以及CH3I反应,分别生成了单电子氧化加成产物3~5,[PCP]Co(II)X(PMe3)[X=Cl(3), Br(4), I(5)]. X射线衍射分析测定了配合物2~6的结构.

关键词: 碳氢键活化, 钳式配合物, 钴配合物

By treating diphosphinito[PCP]-pincer ligand,(Ph2P(ortho-C6H4))2CH2(1) with CoMe(PMe3)4 or CoMe3(PMe3)3 the same Csp3-H bond activation product[PCP]Co(I)(PMe3)(2) was obtained at room temperature. Treatment of 2 with C6Cl6, EtBr or n-BuBr and CH3I gave rise to the single electron oxidation addition products[PCP]Co(II)X(PMe3)[X=Cl(3), Br(4) and I(5)]. The molecular structures of 2~6 were confirmed by X-ray diffraction analysis.

Key words: Csp3-H activation, pincer complex, cobalt complex
