    • There is provided a process for the production of carbonyl compounds, characterized by reacting a diol represented by the formula (1);
      wherein R 1 , R 2 , R 3 and R 4 are the same or different, and independently represent a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted acyl group, a substituted or unsubstituted alkoxycarbonyl group, a substituted or unsubstituted aryloxycarbonyl group, a substituted or unsubstituted aralkyloxycarbonyl group, carboxyl group or a hydrogen atom, or R 1 and R 2 or R 3 and R 4 are bonded together with the carbon atoms to which they are bonded to form a ring , provided that all of R 1 , R 2 , R 3 and R 4 are not hydrogen atoms simultaneously; with bromine or an inorganic bromine compound in the presence of a trivalent bismuth compound and a base to form carbonyl compounds represented by the formula (2);
      wherein R 1 and R 3 are as defined above; and the formula (3);
      wherein R 2 and R 4 are as defined above.
