Aromatic compounds react smoothly with carboxylic acids in the presence of silica gel supported aluminium trichloride to afford the corresponding ketones with high regioselectivity in high to excellent yields. The catalyst is stable (as a bench top catalyst) and can be easily recovered and reused wit...
In order to examine whether or not an acyl group in diacyl peroxide is exchanged by another one, like transacylations in esters and in acid anhydrides, the reaction of acetyl benzoyl peroxide with acetic acid in the presence of sulfuric acid was carried out at 45°C for 5 h. Perbenzoic ...
