Description

General description

CPhos Pd G3 is a modified G3 precatalyst (G3′). It has been synthesized by Buchwald and coworkers from second generation (G2) precatalyst by methylation of the amino group present on biphenyl backbone. It is a useful catalyst for various cross-coupling reactions. They are versatile catalysts. They have long life in solution and are readily soluble in various organic solvents. G3- precatalysts have been employed in various C-N bond forming reactions.
