catalytic performances at low catalytic loading (up to 0.005 mol %) in ring-closingmetathesis (RCM), macro-RCM, ring-closingenynemetathesis (RCEYM), cross-metathesis (CM), ethenolysis and ring-opening crossmetathesis (ROCM). Moreover, up to 95% enantiomeric excess (ee) was obtained in asymmetric ring-opening crossmetathesis (AROCM) and 57% ee was obtained in asymmetric cross-metathesis (ACM).

The synthesis of ruthenium-complexes with cyclic (amino)(barrelene)carbenes (namely CABCs) as ligands is reported. Isolated in moderate to good yields, these new complexes showed impressive thermal stability at 110 °C over several days. Good catalytic performances were demonstrated in various ring-closing metathesis (RCM), macrocyclic–RCM, ring-closing enyne metathesis (RCEYM), cross-metathesis (CM)
报道了以环状(氨基)(桶烯)卡宾(即CABCs)作为配体合成钌配合物。这些新配合物以中等至良好的产率分离,在 110 °C 的几天内表现出令人印象深刻的热稳定性。在各种闭环复分解(RCM)、大环-RCM、闭环烯炔复分解(RCEYM)、交叉复分解(CM)和开环交叉复分解(ROCM)反应中均表现出良好的催化性能。
