ABSTRACT:
Disclosed is a method of fluorinating a substrate having the general formula ##STR1## where each R is independently selected from halogen, alkyl from C.sub.1 to C.sub.12, aryl from C.sub.6 to C.sub.12, alkoxide from C.sub.1 to C.sub.12, aryloxide from C.sub.6 to C.sub.12, nitro, amino, alkylamino from C.sub.1 to C.sub.12, and arylamino from C.sub.6 to C.sub.12, each X is independently selected from halogen and at least one X is chlorine or bromine, each m is independently selected from 0 to 5, n is 0 or 1, p is 0 or 1, q is 0 or 1, and n+p+q is 1. The substrate is heated to a temperature of about 40 to about 100.degree. C. and is reacted with a fluorinating agent in the presence of about 0.05 to about 2 wt % molybdenum trioxide. The composition of the substrate, the catalyst, and the fluorinating agent is also disclosed.
