The Reactions of 3, 7-Dinitrodibenzobromolium Salt with Some Amines

The reactions of 3,7-dinitrodibenzobromolium salt with some amines were studied. A reaction mechanism based on the structure of the major product 6 and the minor product 7 was proposed. The reaction was considered to proceed via a substituted benzyene intermediate.

3,7-二硝基二苯并环状卤鎓盐在碱性条件下的反应机理研究

研究了 3 ,7 二硝基二苯并溴五环盐 ( 1a)与一些伯胺及仲胺的反应 ,其主要产物 6( 2 溴 2′ 烷氨基 4,4′ 二硝基联苯 )与次要产物 7( 2 溴 3′ 烷氨基 4,4′ 二硝基联苯 )互为位置异构体 ,这一结果支持一个以苯炔类化合物 ( 4 )为中间体的反应机理 .进而用蒽成功地捕获了一系列 3 ,7 二硝基二苯并环状卤盐 ( 1a～ 1c)在碱性条件下形成的苯炔类中间体 。
