Abstract
La presente invencion se refiere a los cianuros de halometilbenzoilo I: PH-CO-CN (Ph [sic] = fenilo el cual esta substituido por clorometilo o bromometilo y puede, si se requiere, también llevar 1-4 de otros radicales) que se preparan a partir de cloruros de halometilbenzoilo II PH-Co-C1 (ii), mediante la reaccion II con un compuesto donador de cianuros en presencia de un ácido de Lewis, si se requiere, en un solvente orgánico o diluyente inerte, y luego el aislamiento del producto. Los cianuros de halometilbenzoilo son intermediarios importantes para la síntesis de agentes protectores de las cosechas.
