    Abstract: A process comprising the reaction of an optionally substituted benzene with thiophosgene in the presence of a Friedel-Crafts catalyst for the preparation of the equivalent optionally substituted benzophenthione and benzophenthiones of formula (I), in which X is H, halogen, alkyl, alkoxy, CN, or dialkylamino. The benzophenthiones are converted into the equivalent benzophenone derivatives by hydrolysis or by oxidation.

    Abstract translation: 一种方法,包括在Friedel-Crafts催化剂存在下与任选取代的苯与硫光气的反应,用于制备式(I)的当量任选取代的二苯并噻吩和苯并噻二唑,其中X为H,卤素,烷基,烷氧基, CN或二烷基氨基。 苯并噻吩通过水解或氧化转化为相应的二苯甲酮衍生物。
