Abstract

Ferrocenyl-based unsymmetrical ligands containing di(1-adamantyl)phosphino groups with general formula, Fc(AdP) (RP) and corresponding metal complexes, include metal halide complexes, N-biphenyl metal cationic complexes and R-allyl metal cationic complexes, useful in catalysis. The ligands and complexes overcome problems with conventional catalysts, providing new routes to previously challenging cross-coupling reactions, including C—P coupling, C-Ccoupling and other conventional cross-coupling applications, while being scalable so that they can be provided in sufficient quantity and purity for industrial applications.
