friedel–crafts acylation of aromatic compounds
an efficient method for the friedel–crafts acylation of a wide range of aromatic compounds in good to excellent yields under solvent-free conditions, using iron zirconium phosphate (zpfe) was investigated. the catalyst is easy to prepare and shows interesting catalytic properties. the catalyst was characterized by some instrumental techniques such as xrd, icp-oes, sem and tem. a wide variety of...
متن کاملBiocatalytic Friedel–Crafts Acylation and Fries Reaction
The Friedel-Crafts acylation is commonly used for the synthesis of aryl ketones, and a biocatalytic version, which may benefit from the chemo- and regioselectivity of enzymes, has not yet been introduced. Described here is a bacterial acyltransferase which can catalyze Friedel-Crafts C-acylation of phenolic substrates in buffer without the need of CoA-activated reagents. Conversions reach up to...
متن کاملFriedel–Crafts acylation of 2-methoxynaphthalene over zeolite catalysts
The Friedel–Crafts acylation of 2-methoxynaphthalene was carried out in the liquid-phase batch conditions using Hmordenite, H-beta and H-Y zeolite as catalysts. All the catalysts showed 35–40% conversion in the temperature range of 100–150◦C. 1-Acyl-2-methoxynaphthalene was formed as the primary product. When acetyl chloride was used as the acylating agent, a higher yield of 6-acyl-2-methoxynap...
متن کاملEffective Friedel-Crafts acylation of biotin acid chloride in trifluoromethanesulfonic acid.
Biotin is one of the most useful tags in (bio)analytical science due to its specific interaction with avidin, but is not easy to convert because of its low solubility in most solvents. Friedel-Crafts acylation of biotin acid chloride in triflic acid was examined, and the synthesized derivatives had stronger affinity to avidin than biotin in a binding assay using 2-(4'-hydroxyphenylazo)benzoic a...
متن کاملIntramolecular Friedel–Crafts acylation of acyclic (h-diene)Fe(CO)3 complexes
Intramolecular cyclization of (h-diene)Fe(CO)3 complexes bearing a carboxylic acid chloride functionality at the terminal side chain of the diene ligand produces (s, h-allyl)Fe(CO)3 complexes, whereas treatment of the acid chloride complexes with Et3N and AlCl3 provides (h-diene)Fe(CO)3 complexes containing a cyclopentanone moiety. © 2000 Elsevier Science S.A.
