[1,2,3]Triazolo[4,5‐<i>b</i>]porphyrins: New Building Blocks for Porphyrinic Materials

Abstract

An attractive target: Multiple porphyrin systems (see picture for example) are at the center of many synthetic efforts, and efficient strategies for preparing valuable building blocks for these polycycles are much sought after. Herein such a strategy for the synthesis of [1,2,3]triazolo[4,5-b]porphyrin building blocks is presented.
