Abstract

PROCEDIMIENTO PARA LA OBTENCION DE ARILACETATOS HALOGENADOS. CONSISTE EN REACCIONAR CLORURO DE BENZOILO DE FORMULA (II) EN PRESENCIA DE CLORURO DE ALUMINIO ANHIDRO, CON DICLOROETILENO, PARA OBTENER ARILACETATOS HALOGENADOS DE FORMULA (I) DONDE R ES ALQUILO DE C 1 A 6; X ES HALOGENO, COMO CLORO O FLUOR; X1 ES H O HALOGENO; X2 ES HALOGENO COMO CLORO O FLUOR; Y X3 ES H O HALOGENO COMO FLUOR. LA REACCION SE LLEVA A CABO A UNA TEMPERATURA ENTRE 10 Y 40JC, CON EMPLEO DE UN MOL DE CLORURO DE ALUMINIO ANHIDRO POR MOL DE CLORURO DE BENZOILO Y EN PRESENCIA DE CANTIDADES CATALITICAS DE TRIFENILFOSFINA. SON UTILIZADOS COMO PRODUCTOS INTERMEDIOS PARA LA SINTESIS DE MEDICAMENTOS ANTIBACTERIANOS.
