摘要：

The efficient selective 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) on conversion is also demonstrated. ((C) Wiley-VCH Verlag GmbH & Co.
