Acyl fluoride Friedel-Crafts reactions

Acyl fluoride Friedel-Crafts reactions. Regioselective synthesis of 3-acylacenaphthenes and 2-acyl-6-alkylnaphthalenes. Hyatt, John A.; Raynolds, Peter W. (Eastman Chem. Div., Eastman Kodak Co., Kingsport, TN 37662, USA). J. Org. Chem., 49(2), 384-5 (English) 1984. CODEN: JOCEAH. ISSN: 0022-3263. DOCUMENT TYPE: Journal CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) The replacement of AlCl3 and an acyl chloride with BF3 and an acyl fluoride causes a dramatic change in the regiochem. of acylation of polycyclic arom. hydrocarbons. Regioselective syntheses of 3-acylacenaphthenes (acyl = Me2CHCO, decanoyl, Ac, p-toluoyl) and of 2-acyl-6-methylnaphthalenes (acyl = Me2CHCO, decanoyl, Ac, EtCO) are described. E.There are some commonly used reagents with their cas registry numbers 87969-65-1 and 557-99-3 in this article.g., treating 0.020 mol acenaphthene and 0.025 Me2CHCOF in CH2Cl2 with BF3 at 0-10° 1 h and warming to 25° gives isobutyrylacenaphthenes I-II. Me2CHCOCl-AlCl3 in CH2Cl2 gives I-II. .
