ESR studies on the reactions of sulphite radical anion, SO"3^.^-, with nitroalkane compounds in aqueous solutions - Ozawa, T.; Kwan, T. (Elsevier)
The reactions of the sulphite radical anion, SO"3^.^- (generated from the Ti^3^+-H"2O"2-Na"2SO"3 system at pH 9), in aqueous solutions with some nitroalkane compounds were investigated by using a rapid-mixing flow technique coupled with electron spin resonance (ESR) which can detect the radicals having a lifetime of 5-100 ms. The SO"3^.^- radical added to the double bond of CN in the nitroalkane aci-anions which are the main form of nitroalkanes in aqueous alkaline solutions. From the observed hyperfine splitting constants of the SO"3^.^- adducts of nitroalkane aci-anions, the preferred conformation of the adducts was deduced.
