文摘

A catalytic amount of RuHCl(CO)(PCy₃)₂ (1) activated with AgOTF or AgSbF₆ at room temperature was found to be an effective catalyst system for the hydrovinylation of vinylarenes. Vinylarenes with both electron-donating and electron-withdrawing substituents reacted with ethylene at room temperature to provide the desired 3-arylbutenes in moderate to excellent yield (60−99%) under mild reaction conditions.
