Anodic oxidation of N-aryl-2,2-diphenylacetamides in acetonitrile undergoes three types of bond-cleavage, one between the benzylic carbon and the carbonyl group, the second between a carbonyl and 'N', and the third between the 'N' atom and aryl group. The selectivity of the cleavage and nature of emerged products is highly dependent on the nature of substituent attached to the aryl group. For example
乙腈中N-芳基-2,2-二苯基乙酰胺的阳极氧化会发生三种键断裂,一种在苄基碳和羰基之间,第二种在羰基和'N'之间,第三种在'N'之间原子和芳基。裂解的选择性和出现的产物的性质高度依赖于连接至芳基的取代基的性质。例如,吸电子基团指导苄基-羰基键的断裂,而供电子的取代基则有利于N-芳基键的裂解。获得的产品类型包括二苯甲酮,2,2-二苯基乙酰胺,N-(二苯基亚甲基)乙酰胺,N-(二苯基甲基)乙酰胺,α-内酰胺(1-乙酰基-3,3-二苯基叠氮基-2-one,为1: 1与2,4-二硝基苯胺和苯胺衍生物形成的络合物。
