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.

First claim

The invention claimed is:

1. A method of catalyzing a C—O bond hydrogenolysis reaction comprising:
reacting an organic substrate having at least one carbon-oxygen bond with a reducing agent and catalyst of general formula:
[M(NPR 3 )] n

where:
M is Fe, Co, Cu or Ni;
n is a whole number of at least 2;
the ratio of M to R 3 PN − is 1:1;
R 3 PN − is a monoanioinic phosphoranimide ligand of structure:…
