3-Substituted 2-nitrosoimino-2,3-dihydrobenzothiazoles (1) were reduced with lithium aluminum hydride to give the corresponding thiazolone azines and bis[o-(N-substituted N-formylamino)phenyl] disulfides as major products. Reactions of 1 with some substituted diazomethanes gave the corresponding unsymmetrical azine N-monoxides (16) or azines (17) depending on the structure of the diazomethane.
3-取代的 2-亚硝基亚氨基-2,3-二氢苯并噻唑 (1) 用氢化铝锂还原,得到相应的噻唑酮嗪和双 [o-(N-取代 N-甲酰氨基)苯基] 二硫化物作为主要产物。根据重氮甲烷的结构,1 与一些取代的重氮甲烷反应得到相应的不对称吖嗪 N-一氧化物 (16) 或吖嗪 (17)。
