crystallography. Complex 10 displays a very high thermal stability with a half life of six days at 110 °C in [D8]toluene. Complex 10 was evaluated in various ring‐closing metathesis reactions and ring‐opening metathesis polymerization of dicyclopentadiene, in which it showed a latent behavior with low activity at room temperature and high activity upon thermal activation.
两个新的钌络合物轴承二齿(κ 2 ö,Ç)异丙氧基茚基配体和PPH 3(9)或PCY 3(10中,Cy =环己基)配位体已被合成,并通过完全表征1 H和13 C NMR光谱学和X射线晶体学。络合物10在[D 8 ]甲苯中在110°C下显示出非常高的热稳定性,半衰期为6天。复杂10 在双环戊二烯的各种开环易位反应和开环易位聚合反应中对苯甲酸进行了评估,结果表明该化合物具有潜在的行为,在室温下具有较低的活性,而在热活化后具有较高的活性。
