ÈçÌ⣺After cooling to room temperature, NaCl (2 g) was added to the reaction mixture. This caused the emulsion to separate into two phases. (In the Stille coupling 10 mL of a saturated KF solution was also added). The organic layer was diluted with diethyl ether (50 mL), dried with MgSO4 and concentrated. The ceramic catalyst was extracted with ether (usually 350 mL), dried and concentrated under reduced pressure. The residue was then analyzed for leached palladium by ICP..
