Conclusions
-
1.
Alkanone cyanohydrins of general formula R(CH2)3CR'(OH)CN (R=H or alkyl, R' =alkyl) are efficiently oxidized by the system S2O8 2--Ag+ to 1-cyanoalkoxyl radicals, which then undergo a highly selective rearrangement, with successive migration of the H atom and CN group and oxidation to δ-ketonitriles RCH(CN)CH2CH2COR'.
-
2.
The cyanohydrins of 2-pentanone (Ia), 2-hexanone (Ib), 2-octanone (Ic), and 2-nonanone (Id) are oxidized by the system S2O8 2--Ag+ ∿4-18 times faster than tert-butanol, and in their oxidative ability they fall into the sequence: (Id) > (Ic) > (Ib) > (Ia).
-
3.
A new method was developed for the synthesis of the nitriles of 5-ketoalkanoic acids.
