Studies on the Regioselective Nucleophilic Aromatic Substitution (S<sub>N</sub>Ar) Reaction of 2-Substituted 3,5-Dichloropyrazines
Differences in regioselectivity were observed during the SNAr reaction of amines with unsymmetrical 3,5-dichloropyrazines. This study revealed that when the 2-position of the pyrazine was occupied with an electron-withdrawing group (EWG), nucleophilic attack occurred preferentially at the 5-position. When the 2-position was substituted with an electron-donating group (EDG), nucleophilic attack occurred
