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.
By treating diphosphinito [PCP]-pincer ligand,(Ph2P(ortho-C6H4))2CH2(1) with Co Me(PMe3)4 or Co Me3(PMe3)3the same Csp3—H bond activation product [PCP]Co(I)(PMe3)(2) was obtained at room temperature. Treatment of 2 with C6Cl6, Et Br or n-Bu Br and CH3 I 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.
