Process for selective hydrodefluorination |
| abstract |
ASC/kmf PROCESS FOR SELECTIVE HYDRODEFLUORINATION ABSTRACT A process for the selective hydrodefluorination of a tetrafluorophthalimide compound of the formula I where X is 1 and R is a monovalent organo group; or X is 2 and R is a divalent organo group; comprises reacting (I) the tetrafluorophthalimide with zinc in an aqueous alkali metal hydroxide medium. The product may be hydrolyzed to form 3,4,6-trifluorophthalic acid. |
