A process for the preparation of compounds of the formula: RnAr(CFw'Xp')Z comprises contacting compounds of the formula: RnAr(CFwXp)Z in the liquid phase, with hydrogen fluoride in the presence of molybdenum chloride wherein Ar is aryl R is a substituent on the aryl nucleus selected from the group consisting of aryl, substituted aryl, halogen, alkyl, alkoxy, substituted alkyl, and substituted alkoxy; n is 0 to 9; X is halogen atom other than fluorine; w is 0 to 2; p is 1 to 3; w' is 1 to 3, and is greater than w; p' is 0 to 2, and is less than p; w+p is 3; w'+p' is 3; Z is 1-10; and the maximum value of n+Z is 10.
