Abstract: Phosphoranimide-metal catalysts and their role in hydrodesulfurization and hydrogenation are disclosed. The catalysts comprise of first row transition metals such as nickel, cobalt and iron. The catalysts have a metal to anionic phosphoranimide ratio of 1:1 and have no inactive bulk phase and no dative ancillary ligands. In one embodiment, the catalysts comprise discrete mixed-valent precatalyst clusters, the electronic state of which can be adjusted to optimize catalytic activity. The catalysts catalyze the hydrodesulfurization of a range of sulfur-containing organic compounds under lower temperature and pressure conditions than those conditions commonly used in industrial hydrodesulfurization. The catalysts also catalyze the hydrogenation of substrates comprising at least one carbon-carbon double bond which is not present in an aromatic moiety, although the substrate itself may include an aromatic moiety.

Abstract: Phosphoranimide-metal catalysts and their role in hydrogenation and hydrosilylation are disclosed. The catalysts comprise first row transition metals such as nickel, cobalt or iron. The catalysts have a metal to anionic phosphoranimide ratio of 1:1. This disclosure presents a process for catalytic hydrogenation and hydrosilylation of a range of unsaturated organic compounds under lower temperature and pressure conditions than conditions associated with industrial hydrogenation and hydrosilylation.

Abstract: Phosphoranimide-metal catalysts and their role in C—O bond hydrogenolysis and hydrodeoxygenation (HDO) are disclosed. The catalysts comprise of first row transition metals such as nickel, cobalt and iron. The catalysts have a metal to anionic phosphoranimide ratio of 1:1 and catalyze C—O bond hydrogenolyses of a range of oxygen-containing organic compounds under lower temperature and pressure conditions than those commonly used in industrial hydrodeoxygenation.

Abstract: Phosphoranimide-metal catalysts are disclosed. The catalysts comprise first row transition metals such as nickel, cobalt or iron. The hydrocarbon-soluble catalysts have a metal to anionic phosphoranimide ratio of 1:1, and have no inactive bulk phase and no dative ancillary ligands. The electronic state of the clusters can be adjusted to optimize catalytic activity for a range of commercially important reductive transformations, including hydrodesulfurization. A method of synthesis of these catalysts by anionic metathesis of a halide substituted precursor followed by oxidation is also disclosed.
