Using methylglyoxal as the α-dicarbonyl component in the new pyridazine synthesis described in an earlier publication, two isomeric methyl-5-cyano-pyridazones-(6) are obtained with cyanoacetic acid hydrazide. The position of the methyl groups has been proved.
在较早的出版物中描述的新哒嗪合成中,使用甲基乙二醛作为α-二羰基组分,可以用氰基乙酸酰肼得到两个异构的甲基5-氰基-吡啶并酮-(6)。甲基的位置已被证明。
