Abstract

PROCEDIMIENTO DE OBTENCION DE ACIDOS ARILOXIALCANOICOS Y SUS DERIVADOS. CONSISTE EN HACER REACCIONAR UNA SAL DE METAL ALCALINO, OPTICAMENTE ACTIVA, DE UN ACIDO HALOGENO-2-ALCANOICO CON 2 A 3 ATOMOS DE CARBONO, SOBRE UNA SAL D METAL ALCALINO DE UN FENOL. A CONTINUACION, Y OPCIONALMENTE, SE TRANSFORMA LA SAL OBTENIDA EN EL COMPUESTO ARILOXIALCANOICO OPTICAMENTE ACTIVO. LA SAL DE METAL ALCALINO DE ACIDO ARILOXIALCANOICO SE PREPARA HACIENDO REACCIONAR UNA SOLUCION ACUOSA O HIDROORGANICA DE LA SAL DE METAL ALCALINO, OPTICAMENTE ACTIVA, DEL ACIDO HALOGENO-2-ALCANOICO.
