Abstract
Official abstract text for this publication.
The present invention relates to a transition metal complex having a PNNP4 ligand, which is easy to manufacture and handle and is relatively inexpensively available, and a method for manufacturing the same, as well as a method using this transition metal complex as a catalyst for hydrogenation reduction of ketones, esters and amides to manufacture corresponding alcohols, aldehydes, hemiacetals and hemiaminals, a method using this transition metal complex as a catalyst for oxidation of alcohols, hemiacetals and hemiaminals to manufacture corresponding carbonyl compounds, and a method using this transition metal complex as a catalyst for dehydrogenation condensation between alcohols and amines to manufacture alkylamines.
First claim
Opening claim text (preview).
The invention claimed is: 1. A ruthenium complex having a ligand having one of the following formulas: 2. The ruthenium complex of claim 1 , wherein the ligand has the formula (7 A ). 3. The ruthenium complex of claim 1 , wherein the ligand has the formula (6 A -1). 4. The ruthenium complex of claim 1 , wherein the ligand has the formula (6 A -2). 5. The ruthenium complex of claim 1 , wherein the ligand has the formula (6 A -3). 6. The ruthenium complex of claim 1 , wherein the ligand has the formula (6 A -4). 7. The ruthenium complex of claim 1 , wherein the ligand has the formula (7 B ). 8. The ruthenium complex of claim 1 , wherein the ligand has the formula (6 B -1). 9.
