Popis: A study of solid salts containing cationic complexes of palladium(II) with neutral, weakly complexing ligands resulted in the discovery of the palladium(II)-acetamide-tetrafluoroborate reagent, in which acetamide is present in 20-fold molar excess. It was found that a successful reagent of this type must have a ligand that complexes palladium(II) weakly, but more strongly than does water, with water available for subsequent reaction. Carbon monoxide appears to coordinate with the palladium(II)-acetamide complex, which then reacts with water to form, simultaneously, palladium(O) metal that is black, carbon dioxide, and hydrogen ion. The reagent is described as a visual warning device for the present of carbon monoxide. 5 figs., 1 tab.
