Experimental and quantum-chemical study of the interaction of cyclohexanediones and their monoethylene ketals with hydrogen peroxide
摘要:
The reactivity of cyclohexanediones and their monoethylene ketals with hydrogen peroxide was studied. It was established that 1,2- and 1,3-cyclohexanediones virtually do not react with H2O2, whereas 1,4-cyclohexanedione forms 1,4-dihydroxy-1,4-dihydroperoxycyclohexane. Monoethylene ketals of cyclohexanediones react with hydrogen peroxide to form the corresponding alpha-hydroxy-alpha-hydroperoxides. The stereoelectronic factors determining the difference in reactivity of the carbonyl fragment in cyclohexanone, 1,2-cyclohexanedione, and its monoethylene ketal were analyzed within the framework of the semiempirical quantum chemical method MNDO.
