In contrast to rhodium(lI) stabilized vinylcarbenoids with two electron withdrawing groups, the related mono substituted vinylcarbenoids exhibit reactivity at either the carbenoid center or the vinylogous position. The site of reactivity may be controlled by appropriate catalysts and solvents, leading to the effective synthesis of bicyclic systems by a tandem cyclopropanation/Cope rearrangement sequence
与具有两个吸电子基团的铑(II)稳定的乙烯基类化合物相比,相关的单取代乙烯基类化合物在类胡萝卜素中心或乙烯基位置表现出反应性。反应部位可通过适当的催化剂和溶剂控制,从而通过串联环丙烷化/ Cope重排序列有效合成双环系统。
