  N→Ru配位键长度对新型六价具有钌-氮键螯合环的Hoveyda-Grubbs烯烃复分解催化剂活性的影响

  摘要：

  提出了一种高效的新型Hoveyda-Grubbs催化剂合成方法，该催化剂在六元螯合环中包含N→Ru键。有机金属化合物的合成基于容易获得的2-乙烯基苄胺和1,3-双（2,4,6-三甲基苯基）-2-三氯甲基咪唑烷配体与二氯（3-苯基-1 H -inden-1 ）的相互作用-亚烷基）双（三环己基膦）钌酸盐，它以70-80％的收率提供了目标钌络合物。通过在不同的烯烃交叉复分解（CM）和闭环复分解（RCM）反应中测试催化剂，突出了所获得的螯合物的实用性和潜在应用领域。这些实验显示出很高的催化性能（高达10 –2mol％）在较宽的温度范围内合成的所有结构。通过X射线晶体学对所得钌催化剂的结构特性进行了彻底研究，这使得金属配合物的结构与其催化性能之间具有可靠的关联。结果表明，六元螯合环中钌与氮的键长对催化剂的稳定性和效率影响最大。通常，N→Ru键越短越强，该配合物的稳定性越高，其催化特性越差。反过来，可
