Abstract: A process for preparing acylfluorides by reaction of carbonyl fluoride COF2 with compounds having general formula: T=CR1R2  (I) wherein: T is O or CF2 R1 and R2, equal or different, are F or a R(O)t radical, wherein R=linear or branched C1-C7 (per)fluoroalkyl, optionally containing one or more oxygen atoms, t is an integer equal to zero or 1; wherein a catalyst supported on porous compound is used, the catalyst being selected from: CsF, RbF, KF, AgF, each optionally in admixture with one or more of the others.
