fourteen-membered ring derivatives respectively. Tetralone derivatives are similarly expanded to 6–8 fused ring systems; and indanone derivatives are expanded to 5–7 fused ring systems. The use of both indium and zinc as the metal mediators provided the ring expansion products successfully. The use of water as a solvent was found to be essential for the ring expansion reaction.
已经在水性介质中研究了1,3-二羰基化合物的铟和锡介导的羰基烯丙基化。该研究导致开发了一种新颖的在水中的两原子碳环扩大反应。五元,六元,七元,八元和十二元环被两个碳原子分别扩大为七元,八元,九元,十元和十四元环衍生物。Tetralone衍生物也类似地扩展到6-8个稠环系统。和茚满酮衍生物扩展到5-7个稠环系统。铟和锌作为金属介体的使用成功地提供了扩环产品。发现使用水作为溶剂对于扩环反应是必不可少的。
