A series of square-planar organocobalt complexes of the type [CoR2L2] (R = 2,3,4,6-C6,HCl4 and 2,3,6-C6H2Cl3, L = PEtPh2, PEt2Ph, and PEt3; R = 2,3,5,6-C6HCl4, and 2,6-C6H3Cl2, L = PEt2Ph, PEt3, and dpe) have been prepared in which the electronegativities of the ligand R vary progressively. The reaction of o-C6H4ClMgBr with [CoCl2L2] (L = PEtPh2 PEt2Ph, γ-pic or bipy) did not give air stable compounds
[CoR 2 L 2 ]类型的一系列方形平面有机钴配合物(R = 2,3,4,6-C 6,HCl 4和2,3,6-C 6 H 2 Cl 3,L = PEtPh 2,PEt 2 Ph和PEt 3; R = 2,3,5,6-C 6 HCl 4和2,6-C 6 H 3 Cl 2,L = PEt 2 Ph,PEt 3和dpe)具有制备了其中配体R的电负性逐渐变化的化合物。o -C 6 H 4的反应ClMgBr与[氯化钴2大号2 ](L = PEtPh 2 PET 2 PH,γ-PIC或联吡啶)没有给出在室温下空气中稳定的化合物,但在-78℃下获得的溶液似乎包含正方形平面物种L = PEtPh 2,PET 2 Ph和γ-PIC,和四面体对于L 2 =联吡啶。化合物[CoR 2 L 2 ]趋于正方形或四面体结构的趋势按重要性顺序取决于以下因素:(i)当中性配体为膦时,采用正方形结构;(ii)当L为芳族
