03-Dec-2013 acetylation of alcohols using acetic anhydride but is toxic
Abstract. Friedel Crafts acylation using long chain fatty acid derivatives and biomass-derived furans is the key reaction to produce 'alkyl furan ketones'
tion of methyl ethyl ketone with acetic anhydride by boron trifluoride produces first the enol acetate of 3-methylpentanedione-24 (I) which is then.
Inthis instance acid anhydride molecules function as both the ad- dendum and the acceptor and there is presented for the reaction a mechanism

Reaction between an acid amide and the corresponding acid anhydride leads on the one hand
procedure acetylation is brought about using acetic anhydride with perchloric acid as the catalyst. The reaction takes place rapidly at room temperature.
