本文对化学偶联反应的发生条件加以详细探析,发现化学偶联反应的发生不仅需满足已知的特定热力学条件,而且也应满足一定的动力学条件.若只有两个基元反应偶联,在弛豫时间里,该动力学条件:JT_1A_1~2—JT_2A_2~2>0,这一结果也说明了文献[3]中的结论存在一定的片面性. In this paper, the conditions of chemical coupling reaction are investigated in detail, and it is found that the chemical coupling reaction should not only meet the known specific thermodynamic conditions, but also meet certain kinetic conditions.If only two elementary reactions are coupled, In the relaxation time, the kinetic condition: JT_1A_1 ~ 2-JT_2A_2 ~ 2> 0, this result also shows that the literature [3] the conclusion there is a certain one-sidedness.
