Abstract
A one-step process for hydroformylation of olefins can include iron-catalyzed hydroformylation of olefins. The process can result in the conversion of olefin in the range of 40 to 99%. A reaction mixture includes iron precursor, ligand, substrate and solvent. The reaction mixture can be pressurized with syngas (CO/H2) under constant stirring to obtain a desired aldehyde compound. The ligand can be a monodentate ligand of a phosphines or a phosphite, and the iron precursor can be [HFe(CO)4]−.
Claims9
A one-step process for hydroformylation of olefins, comprising
- charging iron precursor, ligand, substrate, and solvent in a reaction vessel followed by pressurizing the reaction mixture with syngas (CO/H2) under constant stirring at temperature in the range of 70 to 100° C. for a period in the range of 16 to 48 hrs to produce a desired aldehyde compound,
- wherein the conversion of said olefin is in the range of 40 to 99%, the ligand is selected from a group consisting of monodentate ligands of phosphines and phosphites and the iron precursor is [HFe(CO)4]−.
