Abstract

Un procedimiento para la preparación de un derivado del furano caracterizado porque comprende poner en contacto un compuesto insaturado, seleccionado entre el grupo formado por una diolefina de fórmula: **(Fórmula)** donde cada grupo R es H o un grupo alquilo de 1 a 4 átomos de carbono y cada grupo R1 es H, un haluro o un grupo alquilo de 1 a 4 átomos de carbono, con la condición de que el número total de átomos de carbono no pase de 8, y un alqueno monohalogenado o dihalogenado de 4 a 8 átomos de carbono, con un medio acuoso que tiene un pH inferior a 2 aproximadamente y que contiene: (1) yodo procedente de yodo elemental o de un compuesto de yodo, (2) cobre con un grado de oxidación medio comprendido entre 1 y 2 y (3) un agente solubilizante del ión cuproso que sea soluble en agua y forme un complejo soluble en agua con el ión cuproso.
