A protocol for producing 14C2-cis-1,2- dichloroethylene (14C2-cis-DCE) from 14C 2-trichloroethylene (14C2-TCE) was developed as an economical alternative to commercial, custom synthesis of 14C2-cis-DCE. The method uses 5,10,15,20-tetrakis-(4- carboxyphenyl) porphyrin cobalt(II) as a catalyst in the presence of titanium(III) citrate to convert 14C2-TCE to 14C2-cis-DCE as shown in Figure 1. A purge-and-trap technique was used to isolate 14C2-cis-DCE to provide a methanolic stock solution of high purity (97% cis-DCE). The overall 14C2-cis-DCE yield of the process was approximately 53%.
