Acylation Friedel-Ciafts

The ionic liquids as the eco-friendly catalysts and clean reaction medium have also been used for the acylation of polynuclear aromatics. Chen [145-147] and Yuan [148] have investigated the Friedel-Ciafts acylation reactions of anthracene with oxalyl chloride by use of the chloroaluminate ionic Uquids as the catalysts. In these reactions, the ionic liquids exhibited excellent performance as the efficient clean catalysts and reaction media Almost 100% selectivity with 90% yield of... 

In connection with big perspectiveness of polyarylesterketones, the examining of the most popular methods for their production was of interest. The literature data analysis shows that the synthesis of aromatic polyes-terketones can be done by the acylation on Friedel-Ciafts reaction or by reaction of nucleophylic substitution of activated dihalogen-containing aromatic compounds and bisphenolates of alkali metals [224,229]. 

The Friedel-Ciafts acylation reaction is one of the oldest reactions for the preparation of ketones by carbon-carbon bond formation, and is one of the major methods used for the preparation of aromatic ketones. However, acylation by an acid chloride in the presence of a Lewis acid is also applicable to nonaromatic substrates. Whilst it has been known for almost as long as its better-known relative, the...
