The synthesis of novel sulfur-chelated ruthenium benzylidenes afforded latent catalysts with a wider range of activities and new isomeric forms. A ruthenium complex with a tridentate ligand displayed latency for even one of the most reactive ROMP monomers, dicyclopentadiene, while a room temperature latent trifluoromethyl-substituted thioether derivative was shown to be the most active sulfur-chelated
新型硫螯合的钌亚苄基钌的合成提供了具有更广泛活性和新异构形式的潜在催化剂。具有三齿配体的钌配合物甚至对最具活性的ROMP单体之一二环戊二烯也显示出潜伏期,而室温下潜在的三氟甲基取代的硫醚衍生物在更高的复分解反应中被证明是迄今为止活性最高的硫螯合的预催化剂。温度。这些新的配合物拓宽了该系列催化剂的活性谱,使其能够进行多种实际应用,并加深了对强螯合钌烷基亚烷基活化机理的认识。
