Claims
- 1. A method of producing compounds of the formula: ##STR36## which comprises decarboxylating compounds of the formula: ##STR37## in the presence of a base or an activator at a temperature and for a time sufficient to form said compound; wherein
- n=1;
- X'=Cl;
- X=Cl
- a=0 or an integer greater than 0;
- b=0 or an integer greater than 0;
- Y is selected from the group consisting of Z'SO.sub.2, ##STR38## and C.tbd.N; R.sub.f and R'.sub.f are independently selected from the group consisting of F, Cl, a perfluoroalkyl radical and a chlorofluoroalkyl radical;
- Z' is F, Cl, Br, OH, NRR' or OA;
- R and R' are independently selected from the group consisting of hydrogen, an alkyl having one or more carbon atoms and an aryl;
- A is an alkali metal, quaternary nitrogen radical, or R.
- 2. The method of claim 1 where a=0-3; b=0-3; R.sub.f =F or Cl; and R.sub.f '=F or Cl.
- 3. The method of claim 1 wherein the activator is selected from the group consisting of K.sub.2 SO.sub.4, Na.sub.2 SO.sub.4, ZnO, silica and water.
