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.
