DIAZOTIZATION OF SOME AMINODIAZINE N-OXIDES
Jovanovic, Misa V.
, p. 2011 - 2018 (2007/10/02)
Diazotization of a number of aminopyrazine and aminopyrimidine N-oxides affords intermediate diazonium compounds which can be converted to the corresponding bromo and chloro analogs in the presence of the appropriate halide ions.In some instances, electrophilic aromatic substitution takes place prior to the diazotization step.Nucleophilic halogenation accompanying deoxygenation occurs with 2-aminopyrimidine N-oxide in the same manner as described for some 3-amino-1,2,4-triazine 2-oxides.
