cataCXium® Catalysts

cataCXium Ligands are highly effective ligands for palladium catalyzed cross-coupling reactions. Di-adamantylalkylphosphine, called cataCXium A, is a bulky and electron rich phosphine ligand used for Heck and Suzuki coupling, Buchwald-Hartwig amination of arylchlorides, and a-arylation reactions of ketones. In reactions, the catalysts are used with low catalyst loadings under mild conditions. Recently, another class of basic, sterically hindered phosphines featuring phosphino-substituted N-aryl pyrroles (cataCXium P) has shown high catalyst turnover numbers for the Suzuki coupling of both electron rich and electron deficient aryl chlorides.
