The reactions of diphenylcyclopropenone with N-sulfinylanilines in the presence of nickel tetracarbonyl gave pyrrolines, 1,3,4-triphenylpyrroline-2,5-dione (IIIa) and 1-p-tolyl-3,4-diphenylpyrroline-2,5-dione (IIIb). In these reactions, exchanges of C=O for S=O were observed. On the other hand, the reaction with N-sulfinylcyclohexylamine gave a 1:1 cycloadduct, 2-cyclohexyl-4,5-diphenyl-3-isothiazolone-1-oxide
二苯基环丙烯酮与 N-亚磺酰基苯胺在四羰基镍存在下反应生成吡咯啉、1,3,4-三苯基吡咯啉-2,5-二酮 (IIIa) 和 1-p-tolyl-3,4-diphenylpyrroline-2,5-二酮 (IIIb)。在这些反应中,观察到 C=O 与 S=O 的交换。另一方面,与 N-亚磺酰基环己胺的反应得到 1:1 环加合物、2-环己基-4,5-二苯基-3-异噻唑酮-1-氧化物 (IVc),收率 36%,无需交换。
