Abstract

The exhaustive halogenation of the β-positions of Cu(II)-5,10,15,20-tetra-(2,6-difluorophenyl)porphyrin using N-bromosuccinimide and N-chlorosuccinimide in dimethylformamide was carried out. Cu(II)-β-octachloro-(2,3,4,5,6-pentafluorophenyl)porphyrin was synthesized by the reaction of Cu(II)-5,10,15,20-tetra-(2,3,4,5,6-pentafluorophenyl)porphyrin with N-chlorosuccinimide in dimethylformamide. Using the complexation of β-octabromo-5,10,15,20-tetra-(2,6-difluorophenyl)porphyrin, β-octachloro-5,10,15,20-tetra-(2,6-difluorophenyl)porphyrin, and β-octachloro-5,10,15,20-tetra-(2,3,4,5,6-pentafluorophenyl)porphyrin with copper salts in dimethylformamide under mild conditions, the corresponding copper(II) complexes were obtained. The coordination reaction kinetics of β-octabromo-5,10,15,20-tetra-(2,6-difluorophenyl-porphyrin with copper chloride in dimethylformamide has been studied. The kinetic parameters of the reaction were calculated. The obtained compounds were identified by UV-Vis and 1H NMR spectroscopies, mass spectrometry, and elemental analysis. X-ray powder diffraction patterns were obtained for a number of copper complexes.

卤素取代铜(II)四苯基卟啉的合成及光谱性质
用n -溴琥珀酰亚胺和n -氯琥珀酰亚胺在二甲基甲酰胺中对Cu(II)-5,10,15,20-四-(2,6-二氟苯基)卟啉β位进行了彻底卤化反应。以Cu(II)-5,10,15,20-四-(2,3,4,5,6-五氟苯基)卟啉与n -氯丁二酰亚胺为原料,在二甲基甲酰胺中合成Cu(II)-β-八氯-(2,3,4,5,6)五氟苯基)卟啉。将β-八溴-5,10,15,20-四-(2,6-二氟苯基)卟啉、β-八氯-5,10,15,20-四-(2,6-二氟苯基)卟啉和β-八氯-5,10,15,20-四-(2,3,4,5,6-五氟苯基)卟啉在温和条件下与铜盐在二甲基甲酰胺中络合,得到相应的铜(II)配合物。研究了β-八溴-5,10,15,20-四-(2,6-二氟苯卟啉)与氯化铜在二甲基甲酰胺中的配位反应动力学。计算了反应的动力学参数。所得化合物经紫外可见光谱、核磁共振氢谱、质谱和元素分析鉴定。得到了一些铜配合物的x射线粉末衍射图。
