3.
It could be conjectured that 2-methylpyrazine is reacted via a series of dehydrogenations and oxidations to form intermediates pyrazinyl carboxylic acid and pyrazinamide which are then cynadized into 2-cyanopyrazine.
研究2-甲基吡嗪氨氧化催化合成2-氰基吡嗪的催化反应机理后,可知2-甲基吡嗪是通过一系列的脱氢、氧化生成甲醛吡嗪和羧酸吡嗪然后氰化生成产物的,因此优良的催化剂必须由活性及数目合适的脱氢、供[O]及氰化中心组成。

2-吡嗪甲酸
1.
Single crystal of 2-pyrazinecarboxylic acid has been obtained through diffusion method and structurally characterized by single crystal X-ray diffraction analysis.
通过溶液法培养了2-吡嗪甲酸的单晶,利用单晶X-射线衍射法测定了其晶体结构,同时利用元素分析、红外光谱对其进行了表征。
4) 2-Pyrazinecarboxylic acid
2-甲酸吡嗪
5) N-methyl-2-pyrrolecarbonitrile
N-甲基-2-吡咯腈
1.
N-methyl-2-pyrrolealdehyde was prepared through Vilsmeier-haack reaction of N-methylpyrrole,then this aldehyde was converted to N-methyl-2-pyrrolecarbonitrile through oximation and dehydration.
本文介绍了一种制备1-甲基-2-对甲苯甲酰基吡咯的方法,该方法以N-甲基吡咯为起始原料,先经过Vils-meier-haack甲酰化反应制得N-甲基-2-吡咯醛,后者经肟化脱水制得N-甲基-2-吡咯腈,该化合物与格氏试剂对甲苯基溴化镁发生格氏反应,经水解得到1-甲基-2-对甲苯甲酰基吡咯。
