Rhodium(II) acetate-catalyzed decomposition of 1-diazo-3-phenyl-4-(pyrrol-1-yl)-butan-2-one and its p-methoxy derivative resulted in their intramolecular cyclization to form the 6-phenyl-5,6-dihydroindolizin-7(8H)-ones and 1-(pyrrol-1-yl)methylindan-3-ones as major and minor products respectively in high yields (77–89%). The p-nitrophenyldiazo compound cyclized exclusively to the 5,6-dihydroindolizin-7(8H)-one
乙酸铑(II)催化的1-重氮-3-苯基-4-(吡咯-1-基)-丁-2-酮及其对甲氧基衍生物的分解导致它们的分子内环化反应生成6-苯基- 5,6-二氢吲哚嗪7(8H)-酮和1-(吡咯-1-基)甲基茚满-3-酮分别作为主要产物和次要产物,产率高(77-89%)。对硝基苯基重氮化合物仅以76%的产率环化成5,6-二氢吲哚嗪-7(8H)-一。
