The regioselective carbon–carbon bond hydrogenolysis of 1,2-diarylcyclopropanes with water as the hydrogen source in a neutral reaction medium catalyzed by rhodium porphyrin complexes without any sacrificial reductant was successfully achieved. The structures of 1,3-diarylpropane products with complete monodeuterium incorporation at two benzylic positions were confirmed using D₂O.

铑卟啉以水为氢源催化1,2-二芳基环丙烷的区域选择性氢解

在没有任何牺牲还原剂的铑卟啉配合物的催化下，在中性反应介质中成功地实现了以水为氢源的1,2-二芳基环丙烷的区域选择性碳-碳键氢解反应。使用D ₂ O证实了在两个苄基位置完全单氘掺入的1,3-二芳基丙烷产物的结构。
