Deoxydative acetoxylation of 3-methoxy-, 3-phenyl-, 3-methyl-, 3-chloro-, and 3-methoxycarbonylpyrazine 1-oxides furnished predominantly 2-acetoxy-6-substituted pyrazines, some of which were more selectively prepared by addition of zinc bromide and triethylamine to the reaction.Regioselectivity of the acetoxylation is discussed based upon heat of formation by AM1 and AM1-COSMO for all possible isomers of each set.

, p. 1061 - 1067 (2007/10/02)
The reactions of the monoxides of propylpyrazine and phenylpyrazine with phosphoryl chloride or acetic anhydride were investigated.Except in the case of the reaction of 2-propylpyrazine 1-oxide with acetic anhydride, chlorination or acetoxylation occurred
