PROCESS FOR THE PREPARATION OF BENZOPHENTHIONES AND BENZOPHENONES |
摘要 |
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. |
