Pd NPs, obtained in situ from imidazole complexes Pd(im)(2)Cl-2 (im - methylimidazole, butylimidazole), efficiently catalyze the carbonylative Suzuki coupling in water at 80 degrees C and 1 atm of CO. In the catalytic system, used without any additional ligands, differently substituted diaryl ketones were obtained with yields of up to 100% in 1 h. Under slightly modified conditions, Pd NPs catalyze the alkoxycarbonylation of iodobenzenes to esters with high yield.
