Abstract

A simple and efficient method has been developed for the switchable synthesis of directly linked meso-brominated Ni(II) porphyrin dimers through PIFA–BF₃·Et₂O mediated oxidative coupling. The respective syntheses of meso–meso or meso–β singly, doubly, and triply linked porphyrin dimers can be easily realized with the same reagent system.
