  • NOVEL FERROCENE-BASED UNSYMMETRICAL LIGANDS BEARING BULKY DI(ADAMANTLY)PHOSPHINO MOTIF AND THEIR METAL CATALYSTS
    Publication number: 20240199671
    Abstract: Ferrocenyl-based unsymmetrical ligands containing di(1-adamantyl)phosphino groups with general formula, Fc(Ad2P) (R2P) 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, Csp2—Csp3 coupling and other conventional cross-coupling applications, while being scalable so that they can be provided in sufficient quantity and purity for industrial applications.
