专利号:US-9000198-B2 优先权日:2013-05-21 标 题:Mixed-valent transition metal-phosphoranimide catalysts 发明人:BROWN HOUSTON J S; STRYKER JEFFREY MARK; HEBERT DOMINQUE M 权利人:UNIV ALBERTA 摘要: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.
