NN型双齿半夹心Ru(Ⅱ)化合物:无受体脱氢环化合成喹啉和吡咯衍生物的催化剂(英文)
发布时间:2024-04-22 02:45
四个含NN型双齿配体的半夹心(η6-p-cymene)Ru(II)化合物被成功制备.这四个化合物分别为(η6-p-cymene)-Ru(C5H4N-C5H3N-OH)(1),(η6-p-cymene)Ru(C5H4N-CH2-C5H4N)(2),(η6-p-cymene)Ru(C5H4N-CH2-C5H3N-OH)(3)和(η6-p-cymene)Ru(C5H4N-CH2-C5H3N-OCH3)(4).这些化合物通过核磁氢谱、碳谱和元素分析等手段表征,化合物2的结构被X射线单晶衍射证实.将这些化合物应用于催化氨醇与酮的环化反应,其中3的催化效率最高.在0.5mol%化合物3的存在下,制备了一系列喹啉和吡啶衍生物.
