reflux, undergo ring cleavage and formation reactions to give 4-(1-cyclopentenyl)butanoic acids. When the starting ring is six-membered instead, a bicyclic enone results. Mechanistic discussion and some experimental tests are put forth.
当2-(4-酮烷基)
环戊烷酮在回流下经受1
MH 2 SO 4的作用时,发生环裂解和形成反应,得到4-(1-
环戊烯基)
丁酸。当起始环为六元环时,会生成双环烯酮。进行了机理讨论和一些实验测试。
