para-Acetylanisole was determined to be themajor product. This is proven by NMR spectroscopy. IntroductionFriedel-Crafts acylation is a specific example of a larger class of reactions calledelectrophilic aromatic substitutions. Electrophilic aromatic substitution is a type reactionin which an atom ...

Friedel–Crafts acylation of anisole using octanoic acid as a green acylating agent was studied over zeolites free of solvent. It was found that a mixed organic acid, composed of tartaric acid and oxalic acid, modified Hβ (Mix-Hβ) zeolite showed the best catalytic performance among the ...
Friedel – Crafts Acylation: Synthesis of 4-Methoxyacetophenone Introduction Friedel-Crafts acylation of anisole with acetic anhydride was used in this experiement to synthesize 4-methoxyacetophenone with the use of a reflux apparatus. Friedel-Crafts reactions can be done by alkylation‚ which invol...
Friedel-Crafts acylation of anisole over hybrid zeolitic-mesostructured materials 作者:Serrano D P*; Garcia R A; Otero D 来源:Applied Catalysis A: General, 2009, 359(1-2): 69-78. DOI:10.1016/j.apcata.2009.02.013 Anisole acylation
In anisole acylation, PW exhibits very high activity, yielding up to 98% para and 2?% ortho isomer of methoxyacetophenone (MOAP) at 90-110掳C and an AN/AA molar ratio of 10?0. The reaction appears to be heterogeneously catalyzed; no contribution of homogeneous catalysis by HPA was ...

Indium(III) complexes are becoming increasingly widespread in organic chemistry, because of their use as robust Lewis acid catalysts. In(OTf)3 was reported to be an effective catalyst (1 mol.%) for the room-temperature regioselective para-acylation of anisole with acetic anhydride in the presence...
