hand, 6-isopropylfulvene afforded 3-isopropyl-2(3H)-oxepinone or an inseparable mixture with 3-isopropyl-2(7H)-oxepinone. 4-Hydroxy-2-cyclopentenone derivatives were preferentially produced from both fulvenes when the reaction was conducted in methanol using Rose Bengal as a sensitizer.
6-苯基富烯的光氧化得到氧杂环酮衍生物的混合物,从中获得更稳定的3-苯基-2(7H)-氧杂环酮衍生物的纯形式。另一方面,6-异丙基富烯提供 3-异丙基-2(3H)-氧杂环酮或与 3-异丙基-2(7H)-氧杂环酮不可分离的混合物。当反应在甲醇中使用玫瑰红作为敏化剂进行时,4-羟基-2-环戊烯酮衍生物优先由两种富烯产生。
