prepared for the first time via intermolecular olefin cross-metathesis (CM) using 1,3-dimesityl-4,5-dihydro-imidazol-2-ylidene ruthenium alkylidene complex 3 in good yield. A variety of terminal olefins, styrenes, and geminally disubstituted olefins have been successfully employed in these reactions. In addition, CM of vinylphosphonates provide exclusive E olefin stereochemistry.
取代的烯丙基和乙烯基膦酸酯首次通过分子间烯烃交叉复分解 (CM) 使用 1,3-dimesityl-4,5-dihydro-imidazol-2-ylidene 钌亚烷基配合物 3 以良好的收率制备。各种末端烯烃、苯乙烯和孪生双取代烯烃已成功用于这些反应中。此外,乙烯基膦酸酯的 CM 提供独特的 E 烯烃立体化学。
