硝基苯乙酸及其衍生物是重要的有机合成中间体,也是优良的除草剂,它具有高的选择除草活性,尤其是将2、3、4位的硝基苯乙酸混合在一起,其除草效果更好。硝基苯乙酸的合成方法也有不少报道,其最普通的方法是硝基苄氰的水解和苯乙 Nitrophenylacetic acid and its derivatives are important organic synthesis intermediates and are also excellent herbicides with high selective herbicidal activity. In particular, nitrobenzeneacetic acids at positions 2, 3 and 4 are mixed together and their weeding Better results. There are also many reports on the synthesis of nitrophenylacetic acid. The most common method is the hydrolysis of nitrobenzyl cyanide and phenylephrine
