The acylation of a variety of aromatic compounds with benzoyl chloride or its derivatives and catalytic amounts of Al2O3-ZrO2/S2O82- solid superacid affords the corresponding diaryl ketones in good to excellent yields 75-93% at appropriate temperature.
A facile and regioselective base-mediated aerobicoxidative acylation of nitroarenes to access diarylketones undermildconditions has been developed. It features the use of bench-stable and readily available arylacetates as acyl surrogates, and the absence of transition-metals and synthetic oxidants. This protocol involves a cascade CDC/oxidative decarboxylation process.
