Method for producing 2-substituted propionic acid |
| abstract |
(57) [Summary] (Problem corrected) [PROBLEMS] A 2-substituted propionic acid which is more efficient than the conventional method by converting halomethylstyrene to another styrene derivative to reduce self-polymerization in carbonylation And a method for producing the same. SOLUTION: By coupling 2-cyclopentanone carboxylic acid ester with halomethylstyrene in the presence of a base, and reacting the obtained compound with carbon monoxide and water or alcohol in the presence of a metal catalyst. A process for preparing a 2-substituted propionic acid of formula III comprising carbonylation. |
