Abstract
A method including contacting a ligand complex, a metalation compound, and a metal carbonyl in a mixture to form a catalyst. The ligand complex includes one or more of phosphine, imine, and/or hydroxyl groups bound to one or more cyclic structures. The method includes separating the catalyst from the mixture. Contacting the ligand complex with a metalation compound and the metal carbonyl in the mixture to form a catalyst is conducted without isolating any intermediates, performed within a single vessel, and/or performed in a moisture, oxygen, and/or air free environment.
Claims29
A method, comprising:
- a. contacting a ligand complex, a metalation compound, and a metal carbonyl in a reaction mixture to form a catalyst, wherein the ligand complex comprises one or more of phosphine, imine, and/or hydroxyl groups bound to one or more cyclic structures;
- and
- b. separating the catalyst from the reaction mixture.

A method, comprising:
- a. contacting a ligand complex, a metalation compound, and a metal carbonyl in a reaction mixture to form a catalyst, wherein the ligand complex comprises one or more of phosphine, imine, and/or hydroxyl groups bound to one or more cyclic structures, comprising:
- i. contacting the ligand complex and a hydrocarbon solvent to form a first mixture;
- ii. contacting the first mixture and the metalation compound to form a metalated ligand complex in the first mixture;
- and
- iii. contacting the first mixture, a polar solvent, and the metal carbonyl in a second mixture to form the catalyst;
- and
- b. separating the catalyst from the reaction second mixture.
