Abstract
A process for preparing a compound of the formula (Ia): (Ia) in which R1 represents a C1-C6 linear or branched alkyl reactive group, C2-C6 alkenyl reactive group, or aryl reactive group; R3 represents C1-C6 perfluoroalkyl; 0<n<=4; which is characterized in that in a polar aprotic solvent a salt of an acid of the formula (IIa) is reacted with a compound of the formula (III): (IIa) in which R is defined in the above, (III) in which: R3 and n are defined in the above; and X represents a halogen; the reaction is carried out in temperatures ranging from 50 to 280℃, the molar ratio of the compound (III) to the salt of the acid (IIa) being between 0.2 and 10, the concentration of the salt of the acid (IIa) ranging from 5 to 50% (relative to the solvent), a pressure at normal atomospheric pressure or within the range of normal atmospheric pressure, and when the R1 is a C2-C6 alkenyl reactive group, the reaction might take place at pressurized conditions.
