Application

DPPF Pd G4 is a fourth generation (G4) Buchwald precatalyst that is similar to the third generation (G3) precatalysts except that the amino group on the biphenyl backbone is methylated. This modification helps to prevent the limitations found when using the third generation precatalysts. It is air, moisture, and thermally-stable and shows good solubility in common organic solvents.

In Pd-catalyzed C-N cross-coupling reactions, α-branched secondary amines are difficult coupling partners and the desired products are often produced in low yields. In order to provide a robust method for accessing N-aryl α-branched tertiary amines, new catalysts have been designed
