Abstract

Abstract In order to examine the α-substitution of side chains, various derivatives of 2, 5- diisopropyl-and 2, 5-disec-butylpyrazine 1-oxides were subjected to the reaction with phosphoryl chloride and acetic anhydride. Chlorination and acetoxylation were recognized to take place on the pyrazine ring in almost all cases.
