An efficient and economical synthesis of some new fluorine substituted phthalides was accomplished from two γ-keto acids, 2-(4-fluorobenzoyl) benzoic acid and 2-(3, 5-dinitro-4- flurobenzoyl) benzoic acid. Each acid was reacted with various phenolic compounds in presence of catalytic quantity of concentrated sulphuric acid to get the phthalides. The structures of the synthesized compounds were established on the basis of their elemental ...
