Abstract

The synthesis and olefin metathesis activity in protic solvents of 7, a phosphine-free ruthenium alkylidene bound to a hydrophilic solid support are reported. This heterogeneous catalyst promotes relatively efficient ring closing- and cross-metathesis reactions in both methanol and water. The potential utility of homogeneous catalyst 2 for olefin metathesis in methanol is also demonstrated.

摘要

报道了与亲水性固体载体相连的无膦钌亚烷基7在质子溶剂中的合成及烯烃复分解活性。这种多相催化剂在甲醇和水中均能促进相对高效的闭环和交叉复分解反应。还证明了均相催化剂2在甲醇中用于烯烃复分解的潜在效用。
