cross-metathesis (CM) of acrylonitrile using unmodified precatalyst 2 is reported. The use of copper(I) chloride as an additive and phosphane scavenger is described and significant turnover enhancement upon addition of a metallic salt in selective CM is observed for the first time. The influence of catalyst decomposition and other experimental parameters (concentration, amount of acrylonitrile used)
报道了使用未改性的预催化剂 2 对
丙烯腈进行有效的选择性交叉复分解 (CM)。描述了使用
氯化
铜 (I) 作为添加剂和
磷烷清除剂,并首次观察到在选择性 CM 中添加
金属盐后周转率显着提高。还证明了催化剂分解和其他实验参数(浓度、
丙烯腈用量)对转化率的影响。(© Wiley-
