Synthesis route :
Benzophenone can be synthesized by a Friedel-Craft reaction from benzene by reaction with benzoyl chloride in the catalytic presence of aluminum chloride (Lewis acid). Another method consists in reacting benzene with tetrachloromethane, forming alpha,alpha-dichlorodiphenylmethane, which can be hydrolysed to Benzophenone. A last method is to oxidize diphenylmethane.
Synthesis precursor :
Benzophenone is not a precursor for the synthesis of another compound of olfactory interest.
Isomerism :
Benzophenone does not have any isomer commonly used in perfumery.
