• Efficient one-pot transformation of aminoarenes to haloarenes using halodimethylisulfonium halides generated in situ
  作者：Woonphil Baik、Wanqiang Luan、Hyun Joo Lee、Cheol Hun Yoon、Sangho Koo、Byeong Hyo Kim

  DOI：10.1139/v05-026

  日期：2005.3.1

  Halodimethylsulfonium halide 1, which is readily formed in situ from hydrohaloic acid and DMSO, is a good nucleophilic halide. This activated nucleophilic halide rapidly converts aryldiazonium salt prepared in situ by the same hydrohaloic acid and nitrite ion to aryl chlorides, bromides, or iodides in good yield. The combined action of nitrite ion and hydrohaloic acid in DMSO is required for the direct transformation of aromatic amines, which results in the production of aryl halides within 1 h. Substituted compounds with electron-donating or -withdrawing groups or sterically hindered aromatic amines are also smoothly transformed to the corresponding aromatic halides. The only observed by-product is the deaminated arene (usually <7%). The isolated aryldiazonium salts can also be converted to the corresponding aryl halides using 1. The present method offers a facile, one-step procedure for transforming aminoarenes to haloarenes and lacks the environmental pollutants that usually accompany the Sandmeyer reaction using copper halides. Key words: aminoarenes, haloarenes, halodimethylsulfonium halide, halogenation, amination.

  卤二甲基亚砜卤化物1是一种良好的亲核卤化物，可在现场由氢卤酸和二甲亚砜形成。这种活化的亲核卤化物迅速将由相同的氢卤酸和亚硝酸根在现场制备的芳基重氮盐转化为芳基氯化物、溴化物或碘化物，收率较高。在DMSO中，亚硝酸根和氢卤酸的联合作用是直接转化芳香胺的必要条件，从而在1小时内产生芳基卤化物。带有电子给体或吸引基团或有立体位阻的芳香胺的取代化合物也可顺利转化为相应的芳香卤化物。观察到的唯一副产物是去氨基芳烃（通常<7%）。孤立的芳基重氮盐也可以使用1转化为相应的芳基卤化物。该方法提供了一种简便的、一步法的程序，用于将氨基芳烃转化为卤代芳烃，并且不伴随通常伴随使用铜卤化物进行桑迈尔反应的环境污染物。关键词：氨基芳烃，卤代芳烃，卤二甲基亚砜卤化物，卤化，胺化。
