• In conc. H<SUB>2</SUB>SO<SUB>4</SUB> containing the Cu(I) compound, alcohols react with carbon monoxide at room temperature and atmospheric pressure to produce <I>tert</I>-carboxylic acids in high yields. Primary carboxylic acid is not formed. It is assumed that the unstable Cu(I) tricarbonyl ion, Cu(CO)<SUB>3</SUB><SUP>+</SUP>, is transiently formed in conc. H<SUB>2</SUB>SO<SUB>4</SUB>. An amount of the Cu(I) compound as small as 0.2 mol/1 is sufficient. The catalyst is effective at H<SUB>2</SUB>SO<SUB>4</SUB> concentrations above 80%. The reaction rate decreases with a decrease in the H<SUB>2</SUB>SO<SUB>4</SUB> concentration. At H<SUB>2</SUB>SO<SUB>4</SUB> concentrations of less than 80%, no carboxylic acids are obtained.
