Rhodium precursor technology

Johnson Matthey offers a selection of Rh catalyst precursor products for various applications. JM’s rhodium complexes can be combined with a variety of ligand classes such as phosphines, phosphoramidites, pincer ligands, cyclopentadienyls, and NHCs to form active Rh catalyst for a variety of applications.

Example applications for rhodium complexes include asymmetric hydrogenation, hydroformylation, asymmetric C-C and C-N bond formation, hydroboration, cycloadditions, carbonylative synthesis, carbene chemistry and C-H activation.
