阳离子钌-氢化物配合物[(η6-C6H6)(PCy3)(CO)RuH]+BF4 -是芳基酮与环烯烃分子间烯烃反应的高效催化剂。初步机理分析表明，亲电性钌-乙烯基配合物是介导乙烯基C - H键活化和偶联反应脱水烯烃步骤的关键物质。
The cationic ruthenium−hydride complex [(η6-C6H6)(PCy3)(CO)RuH]+BF4−was found to be a highly effective catalyst for the intermolecular olefination reaction of aryl ketones with cycloalkenes. The preliminary mechanistic analysis revealed that an electrophilic ruthenium−vinyl complex is the key species for mediating both vinyl C−H bond activation and the dehydrative olefination steps of the coupling reaction.
