The rhodium-catalyzed cycloisomerization of ester-tethered 1,6-diynes bearing a cyclopropanol moiety produced tetralone/exocyclic diene hybrid molecules with thermodynamically unfavorable alkene geometry. The results of control experiments and density functional theory calculations suggest that the ester tether plays an important role in the efficiency of E/Z isomerization processes.

铑催化的酯键合的1,6-二炔与环丙醇部分的环异构化反应，导致四氢萘酮/外环二烯杂化分子。

带有环丙醇部分的酯基连接的1,6-二炔的铑催化的环异构化反应产生了四烯酮/环外二烯杂化分子，其具有热力学上不利的烯烃几何形状。控制实验和密度泛函理论计算的结果表明，酯系链在E / Z异构化过程的效率中起着重要作用。
