Reactions of various arylamines with either t-butyl thionitrite, t-butyl thionitrate, or p-toluenesulfonyl nitrite in the presence of anhydrous copper(II) halides under mild conditions gave corresponding aryl halides in good yields. This reaction in the presence of such olefins as acrylonitrile, styrene, and acrylic acid gave the corresponding 2-aryl-1-haloethanes as the main products. t-Butyl thionitrite
在无水卤化铜 (II) 存在下,各种芳基胺与亚硫硝酸叔丁酯、亚硫硝酸叔丁酯或对甲苯磺酰亚硝酸酯在温和条件下反应,以良好的收率得到相应的芳基卤化物。在丙烯腈、苯乙烯和丙烯酸等烯烃存在下,该反应得到相应的 2-芳基-1-卤代乙烷作为主要产物。由于硫-氮键较弱,亚硝酸叔丁酯、亚硝酸叔丁酯和对甲苯磺酰亚硝酸酯是比亚硝酸烷基酯或硝酸烷基酯更好的脱氨基试剂。

Several new sulfonyl or sulfonyl derivativives, thionitrates (RSNO2), sulfonyl nitrites (RSO2NO), were successfully isolated by treating corresponding thiols and sulfinic acids with dinitrogen tetraoxide (N2O4). Spectroscopic data of both stable and many rather unstable compounds were determined and compared with those of corresponding alkyl nitrites (RONO) or alkyl nitrates (RONO2). Chemical reactivities
