48 - 118Reaction of Organometallic Compounds with Polyfluorinated BenzeneDerivatives: Synthesis of 1-[3-(2,4-Difluorobenzoyl)-phenyl]-propan-1-one. — Three methods for the preparation of (V) are compared. Whenreacting (III) or (VIII) with 2,4-difluorobenzoyl chloride (IV), a small amount ofa decarbonylation product is observed. Thus, the reaction sequence (VI) → (X)→ (V) is preferred. — (MARTI, JOSEP; BALLART, BERTA; VELASCO,DOLORES; LOPEZ-CALAHORRA, FRANCISCO; Synth. Commun. 30(2000) 16, 3023-3030; Dep. Quim. Org., Fac.
