In the presence of catalytic amounts of cesium chloride, using DMF as solvent, sodium (potassium) carboxylates reacted with α-chloroacetates at room temperature or reacted with alkyl bromides (chlorides) at 60℃ to give the corresponding (α-alkoxyformacyl)methyl carboxylic esters and carboxylic esters in >90% yields. The catalytic mechanism was discussed.

Key words: cesium chloride, sodium (potassium) carboxylates, alkyl bromides (chlorides), esterification
