Fluorobenzene → HCID 18330548, compound

Participants

Reaction Steps

3 g of 2-fluoro-4-bromoiodobenzene, about 0.4 g of PdCl2 and 0.2 g or 5% Pd on carbon, 20 ml of fluorobenzene, and 10 ml of 2M Na2CO3, were added to a 3-neck round bottom flask equipped with a slow nitrogen purge. The mixture was vigorously stirred and 1.21 g of phenylboronic acid in about 5 g of concentrated ethanol was added. The solution was then refluxed at 70°-72° C. The resulting solution was then analyzed by gas chromatography (corrected for sensitivity factors) and it was determined that the desired product, 2-fluoro-4-bromobiphenyl, was produced in 55% yield with about 12% fluoroterphenyl.
