Heteropoly acids are solid inorganic polyacids, with great applications in many areas and can be used either directly as a bulk material or in supported form. The supported form is preferable because of its higher surface area and better accessibility of reactants to the active sites. Based on our previous studies on the use of heteropoly acid catalysts, herein we wish to report a rapid and efficient catalytic procedure for the one-pot synthesis of B-acetamido ketones and esters using tungstophosphoric acid (PW) as bulk and supported on activated carbon. After impregnation of activated carbons with PW, surface area, pore volume, and average pore diameters were decreased. N2 isotherms and pore volume distribution are investigated. Supported PW acid yielded much higher conversion than bulk form. In conclusion, an efficient method for the synthesis of  - acetamido carbonyl compounds is developed in the presence of a new synthesized activated carbon-supported Keggin catalyst. Simple experimental procedure, high yield and selectivity, makes this method useful addition to the present methodologies.
