B01J31/249 - CPC Classification

Classification description:

Catalysts comprising hydrides, coordination complexes or organic compounds containing coordination complexes; Phosphines, i.e. phosphorus bonded to only carbon atoms, or to both carbon and hydrogen atoms, including e.g. sp2-hybridised phosphorus compounds such as phosphabenzene, phosphole or anionic phospholide ligands; Cyclic ligands, including e.g. non-condensed polycyclic ligands, the phosphine-P atom being a ring member or a substituent on the ring comprising condensed ring systems Spiro-condensed ring systems
