Friedel acylation
Webuse of Friedel-Crafts as an alkylation technique, enantioselective Friedel-Crafts reaction could allow for higher-efficiency production of many compounds. The Friedel-Crafts reactions are the focus of so much research because of their widespread utility in many spheres of organic chemistry, and it is likely that research on them will continue ... WebFriedel Crafts Acylation, as the name suggests, is an organic reaction that is used in the addition of acyl substituents to aromatic compounds. This is a coupling reaction that uses electrophilic aromatic substitution in order to substitute the hydrogen atoms present on the aromatic compounds with acyl groups.
