Buchwald Ligands

For Buchwald-Hartwig Cross Coupling Reaction

Buchwald ligands are bulky electron-rich dialkylbiaryl phospines and are known to improve reactivity in palladium catalysis. These highly active reagents have been extensively applied in the synthesis of pharmaceuticals, natural products, polymers, and new materials. The structure of the dialkylbiaryl ligand is directly correlated to the efficiency of catalysts containing these ligands. Sigma-Aldrich is proud to offer a series of Buchwald ligands successfully utilized in reactions including Suzuki-Miyaura coupling, amination, amidation, enolate arylation, Sonogashira coupling and C-O bond formation.

Sigma-Aldrich provides the following Buchwald Portfolio of Precatalysts and Ligands, detailing product applications to cross-coupling reactions.
