Ketenes generated during the thermal decomposition of 5-[(N-aryl/alkylamino)(hydroxyl)methylene]-2,2-dimethyl-1,3-dioxa-4,6-diones react with highly electrophilic iminium ions. The initial [2+2] cycloaddition product rearranges to 2-arylidene malonamide. Mechanistic aspects of the process are presented.
5-[(N-芳基/烷基氨基)(羟基)亚甲基] -2,2-二甲基-1,3-二氧杂-4,6-二酮热分解过程中产生的酮与高亲电性亚胺离子反应。初始的[2 + 2]环加成产物重排为2-亚芳基丙二酰胺。介绍了过程的机械方面。
