A systematic study for the in situ generation of Ru-based metathesis catalysts was described. Assembly of commercially available and inexpensive reagents [Ru(p-cymene)Cl2]2, SIPr·HCl, and n-BuLi led to the formation of 18 electron arene-ruthenium complexes that, in the presence of additives such as alkynes, cyclopropenes, and diazoesters, generated highly selective and efficient catalytic systems applicable
描述了原位生成钌基复分解催化剂的系统研究。组装市售和廉价的试剂[Ru(p- cymene)Cl 2 ] 2,SIPr·HCl和n -BuLi导致形成18种电子芳烃-钌络合物,在存在炔烃,环丙烯等添加剂的情况下和重氮酸酯,产生了适用于各种烯烃复分解转化的高度选择性和高效的催化体系。值得注意的是,我们能够实现油酸甲酯自我复分解的TON生产能力为4500,该反应可以轻松升级至2 kg。
