本文报道了一种绿色且简易的合成氯苯胺灵的方法。以廉价易得且能循环使用的非金属硒作催化剂,以一氧化碳替代剧毒光气作羰基化试剂,通过异丙醇和间氯硝基苯经“一锅法”硒催化氧化还原羰基化反应直接合成氯苯胺灵。催化剂硒的反应过程相转移催化作用使其可回收循环使用。并提出了可能的反应机理。
This paper reports a green and simple method for the synthesis of chloroaniline. A cheap and easily recyclable non-metallic selenium as a catalyst, with carbon monoxide instead of highly toxic phosgene as a carbonylation reagent, isopropanol and m-chloronitrobenzene by the “one pot method” selenium catalytic reduction carbonylation Direct synthesis of chloroaniline reaction. Catalytic selenium phase transfer reaction of the catalytic process so that it can be recycled for recycling. And put forward the possible reaction mechanism.
