The paper describes the synthesis of new 1,3,3-triary-1′-methylspiro[azetidine-2,3′-indoline]-2′,4-diones from reaction of the 2-diazo-1,2-diarylethanones with 3-arylimino-1-methyl-2-indolinones. The compounds have been characterized by satisfactory analytical and spectral (IR, 1H NMR and 13C NMR) data. The diarylketenes, generated in situ from thermal decomposition of the 2-diazo-1,2-diarylethanones
该论文描述了由2-重氮基1,2-二芳基酮与二恶唑酮的反应合成新的1,3,3-triary-1'-甲基螺[氮杂环丁烷-2,3'-二氢吲哚] -2',4-二酮。 3-芳基-1-甲基-2-吲哚满酮。通过令人满意的分析和光谱(IR,1 H NMR和13 C NMR)数据对化合物进行了表征。由2-重氮-1,2-二芳基酮的热分解原位生成的二芳基乙烯酮与偶氮甲碱键优先于羰基反应,导致形成产物。
