Abstract
UN PROCESO PARA OBTENER UN DERIVADO DEL ACIDO CARBOXILICO, REPRESENTADO POR LA FORMULA GENERAL [VIII], (EN LA QUE R1, R2, R3 Y L SON CADA UNO CONFORME A LO DEFINIDO EN LA MEMORIA), QUE COMPRENDE LA REACCION DE UN HALURO DE BENCILO CON UN COMPUESTO DE CIANO, PARA OBTENER UN FENILACETONITRILO, REACCIONANDO EL NITRILO CON UN NITRITO DE ALQUILO, EN PRESENCIA DE UNA BASE, PARA DAR UN HIDROXIIMINOFENILACETONITRILO, REACCIONANDO EL NITRILO HIDROXI CON UN AGENTE ALQUILIZANTE, PARA OBTENER UN ALCOXIIMINOFENILACETONITRILO, HIDROLIZANDO EL NITRILO DE ALCOXI EN PRESENCIA DE UNA BASE, OPCIONALMENTE DESPUES DE LA HIDRATACION Y TRATAMIENTO ACIDO, PARA DAR UN ACIDO - ALCOXIIMINOFENILACETICO, Y FINALMENTE RACCIONANDO EL ACIDO CON UN AGENTE DE HALOGENACION, O CONVIRTIENDO EL ACIDO EN UNA SAL METALICA CORRESPONDIENTE, Y REACCIONANDO LA SAL CON UN AGENTE ALQUILIZANTE, O REACCIONANDO EL ACIDO CON UN ALCOHOL INFERIOR, EN PRESENCIA DE UN CATALIZADOR ACIDICO. DE CONFORMIDAD CON ESTE PROCESO, PUEDEN REALIZARSE LASREACCIONES MEDIANTE FASES RESPECTIVAS, EN CONDICIONES POCO RIGUROSAS, Y EL DERIVADO DE REFERENCIA [VIII] PUEDE PRODUCIRSE SIN RECURRIR A EQUIPO DE VAPOR A GRAN PRESION, EQUIPO MEDIO DE CALOR A TEMPERATURA ELEVADA, NEVERA, Y ASI SUCESIVAMENTE. ADEMAS, ESTE PROCESO ES CONVENIENTE PORQUE CON UN DISOLVENTE UNICO BASTA, SIN NECESIDAD DE USAR VARIOS DISOLVENTES DE CONFORMIDAD CON LAS FASES RESPECTIVAS.
