ruthenium metathesis catalysts bearing fluorinated imidazo[1,5-a]pyridin-3-ylidene carbenes (F-ImPy) were developed for ethenolysis (cross metathesis with ethylene) of methyl oleate. X-ray crystal structure analysis shows Ru–F interaction, and this fluorine substitution appears to be pivotal to have stable ImPy-Ru precatalysts. Ligand structure was varied for high catalyst activity and cross metathesis
开发了一系列带有氟化咪唑并[1,5 - a ]吡啶-3-亚烷基碳烯(F-ImPy)的钌复分解催化剂,用于油酸甲酯的乙烯分解(与乙烯交叉复分解)。X射线晶体结构分析显示Ru-F相互作用,并且这种氟取代对于具有稳定的ImPy-Ru预催化剂至关重要。改变配体结构以在乙烯分解反应中具有高催化剂活性和交叉复分解选择性。F-ImPy-Ru催化剂在乙烯气氛下对油酸甲酯的乙烯分解具有很高的选择性,并具有很强的热稳定性。
