文摘

The metallacyclopentadiene 47a10002">complexC₅Me₅(PPh₃)(Cl)RuCH=CHCH=CH(1) was found to catalyzethe linear coupling reaction of acetylene andacrylonitrileto give predominantly2(E),4(Z),6-heptatrienenitrile(3;TON = 15, 85% selectivity). The coupling reactionisproposed to occur via an initial PPh₃ dissociationfrom1 and the subsequent insertion of acrylonitrile.
