In lab, we combined bromonitrobenzene and phenylboronic acid via Suzuki, and filtered the result through a pipette with MgSO4. I understand that MgSO4 is a dehydrating agent, but I'm not sure why this turned the solution brown to palish yellow. Is the MgSO4 holding onto other contaminants as well? I know it's a purification, but I'm not sure *what* is being purified. Is it grabbing the palladium (we used 1.0mg/ml palladium in H2O)?
Why is MgSO4 used in a Suzuki workup?
