摘要
MoOS_2(S_2CNEt_2)_2是含有Mo(S_2)基团的模型化合物,对它的研究有助于了解某些钼酶活性中心的本质。该化合物的结构研究已有较详尽的报道,而动力学研究的报道甚少。本文着重探讨各种动力学参数与溶剂特性之间的关系。
The reaction kinetics between MoOS2(S2CNEt2)2 and PPh3 was studied in various organic solvents with the aid of the stopped-flow technique. The linear relationships between the kinetic parameters, such as In k, activation energy E, and a function of dielectric constant of solvents (ε- 1)/ (2ε+1) were found. The reaction mechanism is also discussed in this paper. The reaction can be expressed as follows:
