The reaction between carboxylic acids and dialkyl dicarbonates, in the presence
of a weak Lewis acid such as magnesium chloride and the corresponding alcohol as
the solvent, leads to esters in excellent yields. The mechanism involves a
double addition of the acid to the dicarbonate, affording a carboxylic anhydride
and CO2.
