## Abstract ^1^H, ^13^C, ^14^N and ^15^N NMR chemical shifts were used to prove the structures of the products of 2‐chloropyrazine oxidation. It was shown that oxidation by hydrogen peroxide in acetic acid or __m__‐chloroperbenzoic acid leads to the __N__4‐oxide, whereas potassium persulfate in sul
