Reactions between 6-substitued fulvenes and the hydride complex RuHCl(PPh3)3 are described. Treatment of RuHCl(PPh3)3 with fulvenes without sp3-CH protons at the carbon α to the exocyclic carbon of fulvene produces cleanly monosubstituted cyclopentadienyl ruthenium complexes (η5-C5H4R)RuCl(PPh3)2 via hydride transfer to the electrophilic exocyclic carbon of fulvenes. When fulvenes containing sp3-CH
描述了6-取代的富烯和氢化物配合物RuHCl(PPh 3)3之间的反应。RuHCl的治疗(PPH 3)3与没有SP富烯3个-CH质子在碳α到富烯的环外碳产生干净地单取代的环戊二烯基的钌络合物(η 5 -C 5 H ^ 4 R)的RuCl(PPH 3)2通过氢化转移到富烯的亲电环外碳上。当含有SP富烯3被用来-CH质子在α碳的环外碳,反应产生预期的(η 5 -C 5 H ^由于脱氢,4 R)RuCl(PPh 3)2配合物以及少量的乙烯基环戊二烯基钌配合物。
