A new mechanism for the origin of multiple skeletal isomers observed in the cationic dimerization of 1‐decene is proposed, and products that should form based on this mechanism are predicted. A protonated cyclopropyl intermediate appeared to form directly from combination of 2‐decyl carbocation with 1‐decene; formation of this intermediate did not appear to occur via ring closure of a branched secondary
提出了在1-癸烯阳离子二聚反应中观察到的多种骨架异构体起源的新机理,并预测了应基于该机理形成的产物。质子化的环丙基中间体似乎是由2-癸基碳阳离子与1-癸烯的结合直接形成的;中间体的形成似乎不是通过分支的次级碳正离子的闭环发生的。作者提出,质子化的环丙基中间体的快速重复异构化会导致癸烯二聚体中的多个骨架异构体。所提出的机制可以解释先前在癸烯二聚体和丁烯二聚体的混合物中鉴定的结构。版权所有©2012 John Wiley&Sons,Ltd.
