芳香族重氮盐可与糠醛反应,得到芳基糠醛。我们利用这一反应合成了5-间硝基苯基糠醛(Ⅰ)及5-对羟苯基糠醛(Ⅱ)并制备了它们的一些衍生物。按下述反应合成了(Ⅰ)、(Ⅱ),并制得(Ⅰ)、(Ⅱ)的若干衍生物:将(l)用过氧化氢
Aromatic diazonium salts can react with furfural to give aryl furfurals. We used this reaction to synthesize 5-nitrophenylfurfural (Ⅰ) and 5-p-hydroxyphenylfurfural (Ⅱ) and prepare some of their derivatives. (I) and (II) are synthesized according to the following reaction and several derivatives of (I) and (II) are prepared: (1)
