Abstract

O-Carboxylation of the alcohol (ROH) occurred to give alkali alkyl carbonate in a good yield when carbon dioxide was introduced into the mixture of an alkali salt of a weak acid, alcohol, and acetone (or THF) at room temperature under atmospheric pressure. Such alkali salts as PhOM, pR′ C 6 H 4 OM (R′= CH 3, CH 3 O, or Br), Et 2 NCSSM, NaCN, and C 6 H 4 (CO) 2 NK (M= K or Na) were effective. The mixture of HOC 6 H 4 COOM and ROCOOM was ...
