Reaction of the ruthenium acetylide complex Cp(dppe)RuCCCH(OMe)CPh2–CH2CHCMe2 (5a) with oxygen readily gives acetone and the acyl complex 6 in almost quantitative yield. Protonation of 5a is followed by an elimination of MeOH and a hydroxyl addition at Cα in the presence of water to give the hydroxycarbene complex 7a. The structures of the acyl complex 6 and the hydroxycarbene complex 7c are fully
乙炔钌络合物CP(dppe)RuC CCH(OMe)CPh 2 -CH 2 CH CMe 2(5a)与
氧气的反应很容易给出
丙酮酰基复合物6几乎可以定量收率。5a质子化之后消除
甲醇 在存在下,在Cα处有羟基加成
水得到羟基卡宾配合物7a。酰基配合物6和羟基碳烯配合物7c的结构通过单晶X射线衍射分析得到充分表征。
