We have designed a general, inexpensive, and versatile method for the synthesis of (1H-benzo[d]imidazol-2-yl)(phenyl)methanone and the formation of C–N bonds via an aromatic aldehyde and o-phenylenediamine. In the presence of N,N-dimethylformamide/sulfur, (1H-benzo[d]imidazol-2-yl)(phenyl)methanone was obtained; however, in the absence of sulfur, quinoxaline was obtained in 1,4-dioxane. A wide range
我们设计了一种通用,廉价且通用的方法,用于合成(1 H-苯并[ d ]
咪唑-2-基)(苯基)甲酮并通过芳香醛和
邻苯二胺形成C–N键。在N,N-二甲基甲酰胺/
硫的存在下,得到(1H-苯并[ d ]
咪唑-2-基)(苯基)甲酮。然而,在不存在
硫的情况下,在1,4-
二恶烷中获得了
喹喔啉。在温和的条件下获得了广泛的
喹喔啉和(1 H-苯并[ d ]
咪唑-2-基)(苯基)亚甲酮。
