CuAAC in a Distal Pocket: Metal Active‐Template Synthesis of Strapped‐Porphyrin [2]Rotaxanes

Abstract

The synthesis of a porphyrin rotaxane by dipolar cycloaddition takes advantage of the ditopic character of a phenanthroline-strapped porphyrin. The success of the click reaction was conditioned by the presence of both a coordinatively unsaturated metal in the porphyrin and a copper(I) bound to the phenanthroline, pointing at a new "tandem active metal template" mechanism.
