How is 5,6-Dimethyl-1-indanone (CAS: 16440-97-4) typically synthesized?

5,6-Dimethyl-1-indanone can be synthesized through the Wittig reaction where methyl iodide is reacted with indanone in the presence of a phosphonium salt. Alternatively, it can be prepared by the oxidation of 5,6-dimethylindan, often using a combination of sodium hypochlorite and sodium hydroxide under controlled conditions to ensure high selectivity and yield.
