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. (© Wiley‐VCH Verlag GmbH & Co.
