Abstract
A dialkyl dicarbonate is prepared by contacting an alkyl haloformate with an alkali metal carbonate in the presence of a solvating amount of a solvent. The process of the invention does not require a catalyst, is easy to carry out, does not employ particularly hazardous materials, does not require cumbersome purification steps, and provides a high yield of dicarbonate.
