1,3-benzoselenazoles having a heteroatom substituent such as NRR‘, OR, and SR groups at the 2-position was developed by the copper(I)-catalyzed reaction of 2-bromophenyl (1) or 2-iodophenyl (2) isocyanides with selenium and heteroatom nucleophiles. In addition, the synthesis of 2-amino-1,3-benzotellurazoles is also described.
通过铜(I)催化2-溴苯基(1)的反应,开发了一种简单实用的合成方法,该方法合成了一种在2-位具有杂原子取代基(例如NRR',OR和SR基团)的1,3-苯并硒唑或带有硒和杂原子亲核试剂的2-碘苯基(2)异氰化物。另外,还描述了2-氨基-1,3-苯并碲基唑的合成。
