In this paper it is shown that 2-nitro-2′-(β-acetyl) hydrazinodiphenyl sulfides cyclize, via a Smiles rearrangement, to 10-acetylaminophenothiazines, which are inert to alkalis and suffer a strong decomposition by acids. 10-Aminophenothiazine has been obtained by ring closure of 2-bromo-2′-hydrazinodiphenyl sulfide via an assumed benzyne intermediate.
在本文中,表明2-硝基-2'-(β-乙酰基)肼基二苯硫醚通过Smiles重排环化成对碱呈惰性且受酸强烈分解的10-乙酰基氨基吩噻嗪。10-氨基吩噻嗪是通过假定的苯炔中间物使2-溴-2'-肼二苯硫醚闭环而获得的。
