Abstract

SE PONE A PUNTO UN NUEVO PROCEDIMIENTO PARA LA PRODUCCION DE 2-CLORO-5-CLOROMETIL-PIRIDINA. EL PROCEDIMIENTO SE CARACTERIZA PORQUE SE HACEN REACCIONAR DERIVADOS DE 2-ALCOXI-5-ALCOXIMETIL-PIRIDINA CON UN AGENTE DE CLORACION, EVENTUALMENTE EN PRESENCIA DE UN DISOLVENTE Y DE UN ADYUVANTE DE REACCION, A TEMPERATURAS COMPRENDIDAS ENTRE 0 (GRADOS) C Y 200 (GRADOS) C. LAS VENTAJAS DEL PROCEDIMIENTO ESTAN EN EL FACIL ACCESO A LOS NUEVOS DERIVADOS DE 2-ALCOXI-5-ALCOXIMETILPIRIDINA POR REACCION DE 3-DICLOROMETILPIRIDINA CON UN ALCOHOL Y CON LOS CORRESPONDIENTES ALCOHOLATOS DE METAL ALCALINO, A TEMPERATURAS ENTRE 0 (GRADOS) Y 200 (GRADOS) C, ASI COMO EN EL ESCASO NUMERO DE PASOS DE LA SINTESIS Y EN LA UTILIZACION PARA LA SINTESIS DE PRODUCTOS QUIMICOS BARATOS, PUDIENDO UTILIZARSE COMO COMPUESTO BASICO 3-METILPIRIDINA. EL COMPUESTO 2-CLORO-5-CLOROMETIL-PIRIDINA PUEDE UTILIZARSE COMO PRODUCTO INTERMEDIO PARA LA PRODUCCION DE INSECTICIDAS.
