摘要：

The title compound 3 rearranges under very mild conditions to form 4,4-dicyano-8,8-dimethyl-2,6-diphenyl-3,5-diazabicyclo[5.1 .0]octa-2,5-diene 5 (in alcohols) or dicyano[4-aroyl-5,5-dimethyl-2-aryl-1-azacyclopenta-1,3-diene-1-ium-1-yl]methanide 6 (in acetic acid). Azomethine ylide 6 adds to 2 pi-systems to form (3 + 2)-cycloadducts.
