1. A process for the manufacture of a compound of formula R1R2R3C—O—O—CR4R5R6 wherein R1 to R6 are chosen independently from F or a perfluorinated or partially fluorinated linear or branched alkyl group, the process comprising a step of reacting a hypofluorite mixture of R1R2R3COF and R4R5R6COF wherein R1R2R3COF and R4R5R6COF are the same or different, and/or a hypochlorite mixture of R1R2R3CoCl and R4R5R6CoCl, wherein R1R2R3COCl and R4R5R6COCl are the same or different, with an inorganic fluoride in the absence of COF2 and carbonyl fluorides of formula R′R″R′″CC(O)F, wherein R′, R″ and R′″ are selected independently from F or a perfluorinated or partially fluorinated linear or branched alkyl group, wherein the inorganic fluoride is selected from the group consisting of AgF, AgF2, CuF, CuF2, BaF2, CsF, and NiF2 or is a mixture of AgF and AgF2.
