A novel and facile Zn-mediated intramolecular five-membered cyclization of beta-tetraarylporphyrin radicals from beta-bromotetraarylporphyrins.
A novel and facile method for the Zn-mediated intramolecular cyclization of beta-porphyrin radicals has been developed for the convenient and effective construction of newly fused five-membered porphyrin systems from readily available beta-bromotetraarylporphyrins.
