Abstract

La présente invention concerne un procédé d'utilisation de fluorure de carbamoyle comme agent fluorant.Ce procédé consiste à traiter un dérivé porteur d'un carbone halogénophore, au moyen d'un fluorure de carbamoyle dans lequel on soumet ledit dérivé et ledit fluorure de carbamoyle à une température au moins égale à 70°C et où on maintient le rapport entre, d'une part, la somme de l'acide fluorhydrique (HF) et du fluorure de carbamoyle et, d'autre part, la somme des halogènes échangeables, des fonctions isocyanates et du fluorure de carbamoyle [(HF + fluorure de carbamoyle)/(halogène échangeable + isocyanate + fluorure de carbamoyle)] à une valeur au plus égale à 1,2. Catalyse par sel d'étain, d'antimoine et/ou de titane.Application à la synthèse de dérivés fluorés.
