查询词典 nitro-pentaerythrite

In chapter 4 an abnormal reaction that the nitro group of 1-aryl-2-nitroethenescan be easily replaced by the organic moity of FG-RZnI using Ni〓 and tertiaryamine as catalyst was first given. The experimental results show that in the presenceof catalytic amount of Ni〓 and tertiary amines, the reaction of FG-RZnI andl-aryl-2-nitroethenes give the substitution products l-aryl-l-alkene, instead ofMichael addition products.

通过实验发现，在催化量的Ni〓及叔胺催化下， l-硝基-2-芳基乙烯与烷基碘化锌并不进行Michael加成反应，而是发生1-硝基-2-芳基乙烯中硝基被取代的反应，生成了高产率的1-芳基-l-烯烃，由于此反应的原料易得、反应条件温和、产物的产率高，因而是合成l-芳基-1-烯烃的有效方法。
