A series of 3-aryl naphto[2',3':4,5]thiazolo[3,2-b-1,2,4-triazolo-5,10-diones (V) have been prepared by the condensation of bromo lawsone (I) with 5-mercapto-3-substituted 1,2,4-triazole (II) followed by cyclization of the resulting uncyclized products (IV) with alkohol and sulfuric acid. The products are identical with the condensation products of 2,3-dichloro naphthoquinone (III) with 5-mercapto-3-substituted 1,2,4-triazoles in the presence of anhydrous alcohol containing fused sodium acetate.
一系列的3-芳基萘[2',3':4,5]噻唑并[3,2-b-1,2,4-三唑-5,10-二酮](V)是通过溴代洛酮(I)与5-巯基-3-取代的1,2,4-三唑(II)缩合,然后用醇和硫酸环化所得到的未环化产物(IV)制备而成。这些产物与在无水醇中加入融化的乙酸钠的情况下,2,3-二氯萘醌(III)与5-巯基-3-取代的1,2,4-三唑缩合的产物是相同的。
