N-Imidoyl sulfoximide (7) reacted with diphenylcyclopropenone (2) at 130 °C to yield a mixture of 1,2-disubstituted 5,6-diphenyl-4(1H)-pyrimidinone (6) and N-(4-oxo-2-pyrrolin-5-yl)sulfoximide (10), which might be formed by [3+3] and [2+3] cycloaddition reactions between 2 and 7. The yields of 6 and 10 depended on the electronic and steric effects of the substituents of 7.
N-亚氨基亚砜 (7) 在 130 °C 下与二苯基环丙烯酮 (2) 反应生成 1,2-二取代的 5,6-二苯基-4(1H)-嘧啶酮 (6) 和 N-(4-氧代- 2-吡咯啉-5-基)亚砜酰亚胺 (10),可能由 2 和 7 之间的 [3+3] 和 [2+3] 环加成反应形成。 6 和 10 的产率取决于电子和空间效应7的取代基
