Processes for Production of 2-Bromo-2,2-Difluoroethanol and 2-(Alkylcarbonyloxy)-1,1-Difluoroethanesulfonic Acid Salt

Disclosed is a process for producing 2-bromo-2,2-difluoroethanol, which comprises reducing a bromodifluoroacetic acid derivative represented by the formula [1] by using an ate hydride complex as a reducing agent. 2-Bromo-2,2-difluoroethanol thus produced can be used as the starting material to carry out the esterification step, the sulfination step and the oxidation step in this order, thereby producing a 2-alkylcarbonyloxy-1,1-difluoroethanesulfonic acid salt, wherein A represents a substituted or unsubstituted linear, branched or cyclic alkoxy group having 1 to 20 carbon atoms, a substituted or unsubstituted aryloxy group having 6 to 15 carbon atoms, a heteroaryloxy group having 4 to 15 carbon atoms, or a halogen atom.
