%X The radical anions of 2,3-dimethylpyrazine and 2,5-di-t-butyl-3-isopropyipyrazine have been prepared by reducing the parent compound with metallic potassium in 1,2-dimethoxyethane (dme). The e.s.r. spectra were recorded at various temperatures and analysed. For 2,3-dimethylpyrazine the analysis yields information on the structure of the ion pair and the experimental hyperfine splittings give satisfactory agreement with calculated values. In the case of 2,5-di-t-butyl-3-isopropylpyrazine the e.s.r. analysis leads to information concerning the stereospecificity of the B proton of the isopropyl group.
