1,6-二酮在碱性试剂存在下能生成环戊烯衍生物,如1,6-二苯己二酮-1,6(1a)在氢氧化钾的乙醇溶液中,生成1-苯-2-苯甲酰环戊烯(2a)和2-苯-3-苯甲酰环戊烯(3a)[1].1,7-二苯庚二酮-1,7(1b)也生成相应的环己烯的衍生物(2b,3b).[2]

On treatment with sodium ethylate 1,7-diphenylheptandione-1,7 (1b) was converted into a mixture of 1-phenyl-2-benzoylcydohexanol (4b),2-phenyl-3-benzoyloydohexene (8b)and 1-phenyl-2-benzoyloyolohexene (2b).When treated with sodium ethylate, 4b was converted into 8b.
