研究了几种钌卡宾基烯烃复分解催化剂的热分解途径。取代的卡宾通过双分子途径分解，而未取代的卡宾被发现单分子分解。闭环复分解的影响进行了讨论，并比较了几种基于铼的催化剂的寿命。
Thermolytic decomposition pathways were studied for several ruthenium carbene-based olefin metathesis catalysts. Substituted carbenes were found to decompose through bimolecular pathways while the unsubstituted carbene was found to decomposed unimolecularly. Implications for ring-closing metathesis are discussed, and the longevity of several ruthenium-based catalysts are compared.
