heteroaryl halide. Subsequent peracetic acid oxidation of the resultant anion delivered an electrophilic acyl nitrile in situ that readily reacted with added nucleophiles to afford heteroaryl carboxylic acid derivatives. The reaction of the sodium salt of malononitrile with a series of heteroaryl chlorides followed by the subsequent addition of an amine and peracetic acid provided the corresponding heteroaryl
丙二腈可以用作用于经由经碱介导的小号发起的一锅法的羰基部分合成子Ñ一个杂芳基卤化物的氩置换。随后,所得阴离子的过乙酸氧化就地递送亲电酰基腈,其易于与添加的亲核试剂反应以提供杂芳基羧酸衍生物。丙二腈的钠盐与一系列杂芳基氯的反应,随后加入胺和过乙酸,得到相应的杂芳基酰胺。
