Steric effects in 126 may also be responsible for its inertness to the grignard reagent . （126）的空间效应也是它对格氏试剂反应迟钝的原因
The addition of hydrogen bromide involves the attachment of an anionic nucleophile in the final step . 溴化氢加成的最后一步，是负离子亲核试剂的附加。
The exposed silver halide is then converted to metallic silver by an agent in the developer . 在显影液中某种试剂的作用下，已感光的卤化银可转变成金属银。
These cocktails are either made from reagents or purchased in concentrated form and diluted with toluene . 这些混合液或是由试剂配制的或是买来的用甲苯稀释的浓缩剂。
A great number of enzyme and bacterial preparation with a wide variety of trade names have been marketed as agents . 各种各样的商品名的酶和细菌制品，已经作为试剂销售。
A great number of enzyme and bacterial preparations with a wide variety of trade names have been marketed as agents . 各种各样的商品牌号的酵素和细菌制品，已经作为试剂销售。
The latter presumably arises by complexation (120) of the initially formed chemical with grignard reagent . 后者大概是由首先生成的化学物质与格氏试剂的络合产物（120）产生的。
If all the reagents are carefully purified, the gel is water white; no trace of yellow color should be observed . 如果全部试剂都经过仔细的纯化，那么胶体是水白色的，不带一点黄色。
Treatments of pyrylium salts with various nucleophilic reagents allows the production of a host of functionalized derivatives . 如果各种亲核试剂与吡喃盐反应，就可制取许多种带官能基的衍生物。
Because the reaction initiated by the attachment of an electrophile, the process is called an electrophilic addition reaction . 因为反应是由亲电试剂的附加而开始的，所以这个过程叫做亲电加成反应。
