Methanesulfonato{(R)-(-)-1-[(S)-2-(dicyclohexylphosphino)ferrocenyl]ethyldi-t-butylphosphine}(2'-amino-1,1'-biphenyl-2-yl)palladium(II)

Catalyst used for C-O coupling reactions between electron-deficient phenols and functionalized heteroaryl chlorides.

Josiphos SL-J009-1 Pd G3 (Josiphos SL-J009-1-G3-palladacycle) 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. G3 precatalysts 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.
