Abstract
SE TRATA DE UN PROCEDIMIENTO PARA FABRICAR ALQUILBROMUROS AMPLIAMENTE FLUORADOS A PARTIR DE LOS YODUROS CORRESPONDIENTES. EN UN DISOLVENTE DIPOLAR APROTICO SE TRANSFORMAN UN BROMURO QUE SE ENCUENTRA COMO SAL DE UN METAL ALCALINO, O DE UN METAL ALCALINOTERREO O DEL COBRE O DEL AMONIO ITUIR -, CON EL ALQUILYODURO AMPLIAMENTE FLUORADO ENTRE 120 Y 200 GRADOS C. LA TRANSFORMACION PUEDE LLEVARSE A CABO, EN PARTE CON MAYOR APROVECHAMIENTO, DESDE -10 HASTA 120 GRADOS C, CUANDO SE LLEVA A CABO EN PRESENCIA DE UNA SAL ALCALINA CON AL MENOS UN ACIDO SULFINICO DE HIDROXIALCANO CON DE 1 A 5 ATOMOS C. EL NUEVO PROCEDIMIENTO POSIBILITA EL USO DE APARATOS POCO COMPLICADOS, SIN DISPOSITIVOS DE SEGURIDAD ESPECIALES Y NO CONLLEVA PROBLEMAS DE CORROSION.
