Palladium on barium carbonate

Product Information

Molecular Formula:
Pd
Molecular Weight:
106.42
Description
Palladium on barium carbonate (5% Pd/BaCO3) is a palladium catalyst that can be used in the cross-coupling reaction of arenediazonium salts with boronic acid at low catalytic loading. It can also be used as a catalyst in the diastereoselective hydrogenations of the imine for the synthesis of chiral trifluoromethyl benzylamines.
