Various carboxylic esters or amides were prepared in good to excellent yields between carboxylic acids and equimolar amounts of alcohols or amines under very mild conditions using dimethylsulfamoyl chloride (Me₂NSO₂Cl) combined with N,N-dimethylamines. The choice of the sulfamoyl chloride and the amine is crucial for the reactions.
