| titleOfInvention | Process for producing ω-bromoalkylmalonic acid and ω-bromoalkylcarboxylic acid |
| abstract | (57) [Problem] To provide a method for easily and efficiently obtaining ω-bromoalkylmalonic acid and ω-bromoalkylcarboxylic acid which are useful as a raw material for liquid crystal materials and pharmaceuticals. SOLUTION: Formula (I): Br (CH 2 ) n CH (COOR) 2 (I) (wherein R is a methyl group, an ethyl group, a propyl group or an isopropyl group, and n is 2 to 12) ) Expressed by) An alkoxycarbonyl group of a dialkyl bromoalkylmalonate is converted into an α, ω-dibromoalkane represented by the formula (II): Br (CH 2 ) n Br (II) wherein n is the same as defined above. Ω-bromoalkylmalonic acid represented by the formula (III): Br (CH 2 ) n CH (COOH) 2 (III) (wherein n is as defined above) Wherein the ω-bromoalkylmalonic acid represented by the formula (III) obtained by the production method is decarboxylated with hydrobromic acid, and the formula (V): Br (CH 2 ) A process for producing an ω-bromoalkylcarboxylic acid represented by n CH 2 COOH (V), wherein n is the same as described above. |
