| titleOfInvention | Process for the preparation of 2-carboxy-thiolane compounds |
| abstract | 1,219,343. 2-Carboxythiolanes. SOC. NATIONALE DES PETROLES D'AQUITAINE. 1 May, 1968 [8 May, 1967], No. 20671/68. Heading C2C. 2-Carboxythiolane and homologues thereof are prepared by hydrolysis of the corresponding 2-trihalomethylthioalane in an acid medium using 2-6 mols water per mol trihalomethylthiolane. Organic and mineral acids may be used, preferred is acetic acid. An improved yield is obtained by effecting hydrolysis in the presence of an alkali metal salt, particularly one derived from the acid employed, e.g. sodium acetate. Hydrolysis may be effected at 30- 100‹ C. Examples relate to the preparation of thiolane-2-carboxylic acid and 5-methylthiolane- 2-carboxylic acid. |
