Stereochemical features of addition of O- and C-nucleophiles to 5-(Het)aryl-2,3-dicyano-1-ethylpyrazinium salts

Stable σH-adducts of O- and C-nucleophiles were obtained with cations of 5-(het)aryl-2,3-dicyano-1-ethylpyrazinium, and their structure was investigated by X-ray diffraction analysis. Analytical separation was performed of 1,2-dihydropyrazines into individual enantiomers by means of HPLC on columns...
