摘　　要：By using AgNO 3 (NH 4) 2S 2O 8 as irritant agent,2,3 dimethylpyrazine was reacted with carboxylic acid to yield six novel 2,3 dimethyl 5,6 dialkylpyrazine.The structure of these compounds was idetified by elementary analysis,IR, 1HNMR.The conditions of the reation were preliminarily studied.By using AgNO 3 (NH 4) 2S 2O 8 as irritant agent,2,3 dimethylpyrazine was reacted with carboxylic acid to yield six novel 2,3 dimethyl 5,6 dialkylpyrazine.The structure of these compounds was idetified by elementary analysis,IR, 1HNMR.The conditions of the reation were preliminarily studied.
