Abstract:
The present invention provides an industrially advantageous process for producing hydrazone derivative represented by the formula (5), which is shown by the following reaction formula.
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.
