Abstract The substitution reactions of five-co-ordinate [Co(Ph 2 PC 2 H 4 PPh 2 ) 2 Cl]Cl with bipyridine, 1,10-phenanthroline and 2,9 dimethyl-1,10-phenanthroline have been investigated in dichloromethane at a temperature of 25 °C. A detailed mechanism is proposed to account for the kinetic data. Evidence is presented to show that the complex reacts by a dissociative mechanism, with a dissociation
摘要研究了五配位[Co(Ph 2 PC 2 H 4 PPh 2)2 Cl] Cl与联吡啶,1,10-菲咯啉和2,9二甲基-1,10-菲咯啉在二氯甲烷中的取代反应。在25°C的温度下。提出了详细的机制来解释动力学数据。证据表明,络合物通过离解机理发生反应,离解速率常数为62.5 s -1。
