Abstract
A series of highly substituted porphyrin thioethers was synthesized from 2,3,7,8,12,13,17,18-octaethyl-5,10,15,20-tetranitroporphyrin (H2OETNP). The reactions proceeded via a SNAr mechanism with a broad range of aromatic thiols in the presence of a base. This is a rapid way to prepare a large variety of meso-substituted porphyrins from only one precursor. Single crystal X-ray analysis revealed that these new porphyrin thioethers are highly distorted, exhibiting conformational properties that are distinctive of both meso-sulfur substitution and steric overcrowding in general. Additionally, denitration of H2OETNP under basic conditions was investigated, yielding products of stepwise desubstitution. This allowed a comparative X-ray crystallographic study to delineate the successive structural effects of an increasing degree of nitro substitution in the complete series of nitro-substituted octaethylporphyrins.

Sugawara S, Kakui T, Yamamoto Y. Alternative synthetic route toward octaisopropylporphyrins and structural deformation caused by a meso-butyl group. J PORPHYR PHTHALOCYA 2014.

Abstract
A rarely investigated octaisopropylporphyrin (OiPP) was successfully prepared by an alternative synthetic route with organic reactions. Introduction of an electron-donating butyl group at the meso-position of OiPP nickel(II) and copper(II) complexes induced structural perturbation on the porphyrin cores. Structural distortion of nickel(II) complexes decreased slightly upon introduction of a butyl group; however, structural change of the copper complexes showed opposite behavior. These results indicate that structural deformation of the OiPP metal complexes with a meso-substituent was determined by the central metal.
