Abstract

Un 3, 5-dibromo-4-hidroxibenzonitrilo (bromoxinilo) bastante puro se ha preparado en alto rendimiento a partir de 4-hidroxibenzonitrilo utilizando un reactivo de bromación sin daño ecológico que comprende una proporción molar 2:1 de bromuro para sales de bromato en medio ácido acuoso sin ningún catalizador bajo condiciones ambientales sin ningún procedimiento de preparación. El producto 3,5-dibromo-4-hidroxibenzonitrilo se obtuvo en un rendimiento del 91-99% con un punto de fusión de 189-191°C y más del 99 de pureza mediante un análisis cromatográfico gaseoso sin ninguna purificación.
