Reaction of amidyl radicals in sodium peroxydisulfate-metal chloride oxidation systems
TLDR
In this paper, the Hoffmann type rearrangement in a Na2S2O8-NaCl-NaOH system was used to convert the alkanoic acid amides into amines containing one carbon atom less than the initial amides.Abstract:
1.
Unsubstituted alkanoic acid amides R(CH2)4CONH2 (R=H or alkyl) convert in Na2S2O8-CuCl2 and Na2S2O8-NaCl oxidation systems via intermediate amidyl radicals R(CH2)4C(O)NH intoγ- and δ-lactones with a considerable predominance ofγ-lactones.
2.
Monoalkyl amides of alkanoic acids are lactonized to an inappreciable extent by the action of the S2O82−-Cl− system; N,N-diethyl valeramide undergoes oxidative dealkylation into N-alkyl valeramide.
3.
As the result of an oxidative, Hoffmann type rearrangement in a Na2S2O8-NaCl-NaOH system, unsubstituted alkanoic acid amides convert into amines containing one carbon atom less than the initial amides.read more
