Thermal decomposition of a variety of 1,3-benzodithiol-2-yl azides (2), easily obtainable from 1,3-benzodithiolylium salts and sodium azide, gives 1,4,2-benzodithiazines (3) in good yields, thus providing a general synthetic route to these compounds.
从1,3-苯并二硫代lyl盐和叠氮化钠容易获得的各种1,3,3-苯并二硫基-2-基叠氮化物(2)的热分解可得到高收率的1,4,2-苯并二噻嗪(3),因此可提供这些化合物的一般合成途径。
