Switchable regioselectivity in the PIFA-BF3·Et2O mediated oxidative coupling of meso-brominated Ni(II) porphyrin

Org Biomol Chem. 2014 Sep 28;12(36):6990-3. doi: 10.1039/c4ob01517g.

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.
