Application
Iron/dppbz-catalyzed Decarboxylative Couplings of Active Esters
In a screwed-capped vial active ester (0.1 mmol), Fe(acac)3 (0.005 – 0.04 mmol) and dppbz (0.006 – 0.048 mmol) are weighed. The vial is then sealed, evacuated and back-filled with Ar. Then, 0.5 mL of distilled THF is added. The mixture is stirred for 5 minutes under Ar and diarylzinc reagent in THF (ca. 0.3 mol/L, 0.15 – 0.25 mmol) is added in one portion at 0 - 25 °C to the mixture and stirred at the same temperature for 1 h. After this time, the reaction is quenched with 1 mol/L HClaq, sat. NH4Claq or H2O and diluted with diethyl ether. The organic layer is separated and dried over Na2SO4 anhydrous, filtered and evaporated to dryness. Pure products are obtained after column chromatography or preparative TLC.
