| 摘 要： | 测定了化合物(Ph2PR)3Co(C5Cl5)2(R=Et,n-Pr)在苯溶液中型转化的热力学和动力学参数,讨论了这种涉及附加配位的新型转化平衡.初始和平衡的八面体构型有不同的附加配位,苯基邻位氢配位比R基端位氢配位更为稳定.四面体构型的稳定性较低,构型转化主要受R基的推动.

| Abstract: | The thermodn. and kinetic parameters of configuration transformation of compounds (Ph2PR)2Co(C6Cl5)2 (R = Et, Pr) in benzene solution have been determine This new type of equilibrium of configuration transformation involving intramol. addition coordination was discussed. Initial and equilibrium octahedral configurations have different addition coordination; the coordination involving Ph ortho-hydrogen is more stable than that involving terminal hydrogen of the R group. The stability of tetrahedral configuration is lower; the configurational transformation is primarily dependent on the size of R groups. |
