| Description
| - In the frame of studies of molecules with two redox centers, two isomeric monooximes derived from aryl-alkyl 1,2-diketones were electrochemically investigated. Whereas 1-phenyl-2-oxo-1-oximinopropane is reduced in acidic media according to the mechanism typical for oximes, that means by fou electrons yielding aminoketone, which is further reduced bielectronically under splitting of ammonia, its isomer 1-phenyl-1-oxo-2-oximinopropane is reduced to the stable 1-hydroxy-2-aminoolefine (enol form) and this corresponds to the reduction mechanism of benzil. It is surprising that the unsymmetric molecule behaves like the symmetric one. Basing on the electrochemical data and their correlation with quantum chemical calculations it was possible to explain this phenomenon.

- V rámci studia molekul se dvěma redox centry byly studovány dva izomérní mnooximy odvozené od aryl alkyl-1,2-diketonu. Zatímco 1-fenyl-2-oxo-1-oximinopropan se v kyselém prostředí redukuje mechanismem typickým pro oximy, tedy čtyřmi elektrony na aminoketon, který pak v druhém kroku ztrácí reduktivně aminoskupinu, jeho izomér 1-fenyl-1-oxo-2-oximinopropan se redukuje na dále neredukovatelný 1-hydroxy-2-aminoolefin (enol forma), což je analogické redukci benzilu. Zde je zvláště překvapivé, že nesymetrická molekula se redukuje mechanismem typickým pro molekuly symetrické. Na základě elektrochemických dat a jejich korelace s kvantovými výpočty se podařilo důvod tohoto jevu vysvětlit. (cs)
