Reaction Conditions:

Stage #1:2,5-dichlorobenzyl alcohol with cobalt ferrite in water for 0.0333333 h;
Stage #2: with oxone(R) in water at 20; for 0.75 h;

Steps:

General Procedure for the Oxidation of Alcohol
General procedure: Alcohol (1 mmol), water (1 mL), and CoFe2O4 MNPs (11.8mg, 5 mol %) were added to a round-bottomed flask. The reaction mixture was stirred for the two minutes, and then oxone (0.6 mmol) was added in three portions. The reaction mixture was placed at room temperature and stirred for the specified time (Table 5). The reaction was followed by TLC (EtOAc-cyclohexane, 2:10). After the completion of the reaction, the product was extracted in dichloromethane. The solvent was evaporated under reduced pressure to give the corresponding aromatic products. Purification of the residue using plate chromatography (silica gel) provided the pure carbonyl compounds. The aliphatic products in dichloromethane was dried with anhydrous MgSO4 and detected by GC-FID.
