The ruthenium catalyst derived from Ru3(CO)12 and triphos [Ph2P(CH2CH2PPh2)2] promotes the direct C-C coupling of isoprene with aryl substituted hydantoins 1a–1f at the diene C4-position to furnish products of n-prenylation 2a–2f. A mechanism involving hydantoin dehydrogenation followed by diene-imine oxidative coupling to furnish a transient aza-ruthencyclopentene is proposed.
钌催化剂衍生自 Ru3(CO)12 和三膦 [Ph2P(CH2CH2PPh2)2]，可促进异戊二烯与取代芳基海因 1a-1f 在二烯 C4-位的直接 C-C 偶联，生成 n-戊烯基化产物 2a-2f。提出了一种涉及海因脱氢，随后二烯-亚胺氧化偶联生成瞬态氮杂钌环戊烯的反应机制。
