And because these materials are so prolific, because they're found in so many places, there's one other place you'll find this material, styrene, which is made from benzene, a known carcinogen.

Acetone and acetic anhydride upon the addition of BF3 catalyst (CH3CO)2O CH3C(O)CH3 CH3C(O)CH2C(O)CH3A second synthesis involves the base catalyzed condensation of acetone and ethyl acetate, followed by acidification NaOEt EtO2CCH3 CH3C(O)CH3 NaCH3C(O)CHC(O)CH3 2 EtOH NaCH3C(O)CHC(O)CH3 HCl CH3C(O)CH2C(O)CH3 NaClBecause of the ease of these syntheses, many analogues of acetylacetonates are known.
