1,4-Diazabicyclo[2,2,2]octane (DABCO) is easily chlorinated and gives a complex which efficiently converts aliphatic and aromatic oximes, phenylhydrazones and semicarbazones to their corresponding carbonyl compounds in water at 50°C in high yield. This reagent can also be used for conversion of thiols to their compounding disulfide under the same reaction conditions. DABCO is quantitatively recovered
1,4-二氮杂双环 [2,2,2] 辛烷 (DABCO) 很容易氯化,生成的络合物可在 50°C 的水中以高产率有效地将脂肪族和芳香族肟、苯腙和缩氨基脲转化为相应的羰基化合物。该试剂还可用于在相同反应条件下将硫醇转化为其复合二硫化物。DABCO 被定量回收,可以再氯化和重复使用多次。
