nucleophilic

1.The experiment consist of two parts :the first one research nucleophilic addition of m-dinitrobenzene, nucleophilic reagent is benzyl cyanide;

实验分两部分：第一部分研究了间二硝基苯的亲核加成反应，亲核试基腈；

2.General approaches involve the nucleophilic cycloalkylation, carbenoids addition of certain amino acid derivatives and derivatization from simple cyclopropane compounds.

制备方法包括对简单氨基酸衍物的亲核烷基、类卡宾加成以及简单丙烷物的衍成等。

3.By nucleophilic addition and reductive cyclization reaction of the three intermediates, respectively, some azo-heterocyclic derivatives containing a rosinyl skeleton were obtained.

该3个中间体分别经过亲核取代、还原关反应后，得到了一些脱氢松香酸甲酯含氮杂衍物；

4.Based on these results and the ESI-MS data, the mechanism of sulfoxidation was proposed to be intramolecular nucleophilic oxygen transfer to a coordinated sulfide.

基于这些结果和电喷雾质谱(ESI-MS)数据，亚砜反应的机理推测分子内亲核氧转移到络的硫醚底物上。
