Process for the preparation of a fluorine containing organic molecule, which process comprises the steps of a) preparation of a compound of the formula (I) wherein R1, R2 and R3 are independently hydrogen, fluor or an optionally fluorinated hydrocarbon group by feeding a compound of the formula (II) wherein R1, R2 and R3 are defined as above, and hydrogen bromide into a reaction zone, thereby producing a reaction mixture containing the compound of formula (II) and hydrogen bromide and irradiating said reaction mixture with UV light, and b) substituting the bromo atom in the compound of the formula (I) with another functional group to obtain the fluorine containing organic molecule. The invention allows also in particular for obtaining substantially anhydrous fluoroalcohols. The preparation of alcohols analogous to the bromides of formula (I) from the corresponding esters is also disclosed.
制备含
