  • Molecular Structure of a Free-Base β-Octaiodo-meso-tetraarylporphyrin. A Rational Route to cis Porphyrin Tautomers?
    Crystal Growth & Design, 2018
    Co-Authors: Ivar K. Thomassen, Laura J. Mccormick, Abhik Ghosh

    Abstract:

    Although a cis tautomer has long been invoked as an intermediate in porphyrin tautomerism, the first such species was only recently isolated and structurally characterized in the form of a β-heptakis(trifluoromethyl)-meso-tetraarylporphyrin. Reported herein is the molecular structure of a β-octaiodo-meso-tetraarylporphyrin solvate, which also exhibits a cis tautomeric structure. Both structures implicate two factors as critical to the stabilization of the cis tautomeric form—a free-base porphyrin that is naturally strongly saddled on steric grounds and a hydroxylic or Amphiprotic Solvent that can provide hydrogen-bonded N–H···X-H···N (X = O in both the above examples) straps connecting the central NH groups with the antipodal unprotonated nitrogens. The results raise the prospect that a rational strategy affording cis porphyrin tautomers in a predictable manner may be within reach.

    has long been invoked
    as an intermediate in porphyrin tautomerism, the first such species
    was only recently isolated and structurally characterized in the form
    of a β-heptakis­(trifluoromethyl)-meso-tetraarylporphyrin.
    Reported herein is the molecular structure of a β-octaiodo-meso-tetraarylporphyrin solvate, which also exhibits a cis tautomeric structure. Both structures implicate two
    factors as critical to the stabilization of the cis tautomeric forma free-base porphyrin that is naturally strongly
    saddled on steric grounds and a hydroxylic or Amphiprotic Solvent
    that can provide hydrogen-bonded N–H···X-H···N
    (X = O in both the above examples) straps connecting the central NH
