Abstract

Acylation reactions are one of the most important group of reactions. The acylation of ketones is one of these. A variety of methods exist in the literature for the synthesis of β- diketones. For example, the reaction of ketone metal enolates with acyl chlorides2 or acyl cyanides3 (eq 1, X) Cl, CN), the acylation of enamines, 4 and the direct BF3 acylation of ketones5 are some reactions which preferentially lead to C-acylated ketones (2) usually ...
