Abstract
There is provided a method for producing a catalyst liquid containing a Group 6 to 11 transition metal catalyst in which the transition metal catalyst can be prevented from being blackened during storage, the method including performing addition of an alkenyl compound and addition of a phosphorus ligand, and then performing addition of a Group 6 to 11 transition metal catalyst
Claims3
A method for producing a catalyst liquid, comprising
- performing addition of an alkenyl compound and a phosphorus ligand to a solvent, then
- performing addition of a Group 6 to 11 transition metal catalyst, and then
- stirring at room temperature, wherein the alkenyl compound, the phosphorus ligand, and the Group 6 to 11 transition metal catalyst are added in that order;
- the alkenyl compound is 2,7-octadien-1-ol;
- the phosphorus ligand is triethylamine 3-(diphenylphosphino)benzenesulfonate;
- the Group 6 to 11 transition metal catalyst is palladium acetate;
- and the solvent is at least one selected from sulfolane and water.
