Reactions of 2-bromoesters and styrenes underwent a [2+1] cycloaddition reaction,i.e., cyclopropanation, to produce donor–acceptor (D–A) cyclopropanes through a radical addition-ring closure process. In this reaction, the combination of copper(ii) complex and amines is found to be a good ...

The [2+2] cycloaddition [2+2]周环加成 …… 按照之前讲的,会分出前过渡金属(d电子数较少的)和后过渡金属(d电子数较多的),其中,后过渡金属的反应以Pd最常见,之后会介绍大部分d区过渡元素的反应,Y、Nb、Tc、Re、Ir等不常见的不会讲,Zn、Cd、Cu、Hg、Ag等一些基础化学中介绍过的反应也不会细讲。
