Hg(CF3CO2)(2)与金属卟啉的反应选择性地产生汞化卟啉，该反应出人意料地发生在最受阻的β (B)-位置；这种行为与卟啉通常的亲电取代反应形成鲜明对比，后者的反应产生中位取代卟啉；所得的汞化卟啉对过渡金属催化的偶联反应（如Mizoroki-Heck反应）具有活性。
The reaction of Hg(CF3CO2)(2) with metalloporphyrins produces mercurated porphyrins regioselectively, the reaction, surprisingly occurring at the most hindered beta(B)-position; this behavior is in marked contrast to the usual electrophilic substitution reactions of porphyrins, whose reactions produce meso-substituted porphyrins; the obtained mercurated porphyrins are active to transition metal-catalyzed coupling reactions, such as the Mizoroki-Heck reaction.
