摘要

在阳离子 Ru 复合物的催化下,通过对壬二烯进行加氢乙烯化反应制备了 (1R,3R,5S,Z)-2-亚乙基-6,6-二甲基-3-乙烯基双环[3.1.1]庚烷。通过 1H 和 13C-NMR 光谱(包括 2D-COSY 和 2D-NOESY 光谱)、光学旋转和燃烧分析对其结构进行了全面表征。与之前报道的用这种催化剂对 1-乙烯基环烷烃进行 1,2-氢乙烯基化反应不同,与壬二烯的反应是通过乙烯的 1,4-加成反应进行的。

(1R,3R,5S,Z)-2-Ethylidene-6,6-dimethyl-3-vinylbicyclo[3.1.1]-heptane
(1R,3R,5S,Z)-2-ethylidene-6,6-dimethyl-3-vinylbicyclo[3.1.1]heptane was prepared by hydrovinylation of nopadiene catalyzed by a cationic Ru complex. The structure was fully characterized by 1H- and 13C-NMR spectroscopy, including 2D-COSY and 2D-NOESY spectra, optical rotation, and combustion analysis. In contrast to the previously reported 1,2-hydrovinylation of 1-vinylcycloalkenes by this catalyst, the reaction with nopadiene proceeds by 1,4-addition of ethylene.
