Transformation of Nitro-5,10,15,20-tetraarylporphyrins into their Amino/Nitro-Functionalized Derivatives

A synthesis of amino-functionalized porphyrins (in meso-aryl rings), utilizing nitro-meso- tetraarylporphyrin complexes [Zn(II), Cu(II), and Ni(II)] and vicarious nucleophilic substitution of hydrogen reaction (VNS) is described.
