Synthesis Of 2-Benzoyl-3,4,5,6-Tetrasubstitutedbenzoic Acid From Tetrasubstituted Phthalic Anhydride Using Organometalics

The reactions of phenylcoppermagnesium and phenylmagnesium bromide reagents with perchlorophthalic anhydride were investigated. Along with 2-benzoyl-3,4,5,6- tetrachlorobenzoic acid, five other substituted products were isolated and their structure were determined by detailed spectroscopic studies.
