substitution (SNAr) reactions of N-(2-bromo-3-nitrobenzyl)aniline (18), N-(2-bromo-3-nitrobenzyl)-4-methylaniline (19) and N-(2-bromo-3-nitrobenzyl)-4-nitroaniline (20) with [nBuSeNa] afford N-[2-(butylselanyl)-3-nitrobenzyl]aniline (21), N-[2-(butylselanyl)-3-nitrobenzyl]-4-methylaniline (22) and N-[2-(butylselanyl)-3-nitrobenzyl]-4-nitroaniline (23), respectively. The bromination of 21 results in the formation
N-(2-bromo-3-nitrobenzyl)aniline (18), N-(2-bromo-3-nitrobenzyl)-4-methylaniline (19) 和 N-(2-bromo -3-硝基苄基)-4-硝基苯胺 (20) 与 [nBuSeNa] 得到 N-[2-(丁基硒基)-3-硝基苄基]苯胺 (21), N-[2-(丁基硒基)-3-硝基苄基]-4 -甲基苯胺 (22) 和 N-[2-(丁基硒基)-3-硝基苄基]-4-硝基苯胺 (23)。21 的溴化导致环状异硒唑啉 7-硝基-2-苯基-2,3-二氢苯并异硒唑 (27) 和 2-(4-溴苯基)-7-硝基-2,3-二氢苯并异硒唑 (28) 的形成。22 的溴化得到异硒唑啉 2-(4-methylphenyl)-7-nitro-2,3-dihydrobenzisoselenazole (29) 和 2-(2-bromo-4-m
