Attempted deoxygenation of 2-aminopyrazine 1-oxide with HF under the diazotization conditions yielded a coupling reaction product, 2,2'-bispyrazyltriazine 1,1'-dioxide.Similarly, diazotization of 2-aminopyrimidine 1-oxide in the presence of hydrofluoric acid gave a nucleophilic hydroxylative-deoxygenation product, 5-hydroxy-2-pyrimidinediozotic acid.
