concerted reaction

英 [kənˈsɜːtɪd riˈækʃn]

美 [kənˈsɜːrtɪd riˈækʃn]

协同反应

The third is concerted one. The theoretical study results show that the favorite exo and endo reaction paths of 1,3-cyclohexadiene with propylene are the stepwise processes via biradical intermediates, in which the terminal carbon of propylene attacks 1,3-cyclohexadiene at the first step.
经计算研究表明：1,3-环己二烯与丙烯生成exo和endo产物的有利途径为经过一个双自由基中间体的分步过程，由丙烯端位碳原子先进攻的分步过程最为容易。
The Derivation of Selection Rules for Concerted Reaction
关于协同反应选择定则的推导
It is found that the titled reaction is a concerted but nonsynchronous reaction, the formation of H-H bond is ahead the breaking of C-H bond.
研究结果表明乙炔加氢反应是一协同的非同步反应，H-H键的生成早于C-H键的断裂。
In the concerted mechanism, two ethylene molecules co-adsorb on the acid site. The reaction proceeds via simultaneous protonation and formation of C-C bond to give the butoxide product.
对于同步反应机理，两个乙烯分子共同吸附在分子筛酸性位，然后质子化和分子间C-C键结合同时进行，形成表面丁醇盐产物。
