The invention provides a method for preparing aldehyde/ketone by catalyzing alcohol oxidation with iron salt: after mixing the compound shown in the substrate formula (I), catalyst iron salt, cocatalyst TEMPO, amino acid ligand and solvent, Stirring under medium reflux for 1 to 60 hours, and then the reaction solution is post-treated to obtain the compound shown in product formula (II); the present invention uses cheap, easy-to-obtain, and environmentally friendly iron salt as a catalyst; uses abundant resources in nature, is cheap and easy to obtain and Amino acids that are easy to modify are used as ligands; the reaction substrate has wide applicability, and primary benzyl alcohol, secondary benzyl alcohol, allyl alcohol and heterocyclic aromatic alcohols can all be converted into corresponding aldehydes in high yields by using the oxidation system of the present invention ( ketone). |
