Synthesis and characterisation of new porphyrazinato magnesium containing macrobicyclic moieties
Novel porphyrazinato magnesium (MgPz) containing symmetrically four diaza-tetrathia-macrobicycles on peripheral positions was synthesized by the cyclotetramerisation reaction of 5,8,16,23-tetrathia-1,12-diazabicyclo[9.7.7]pentacosane-6-en-6,7-dicarbodinitril (9), which was prepared
by sequence reaction of N-tosyl-bis[3-bis(tosyloxypropyl)] amine (1) and disodium cis-1,2-dicyano-1,2-ethylenedithiolate (8). Elemental analysis, IR, NMR, MS and UV–vis data confirmed the ability of bulky cryptand moieties to induce steric isolation of Pz
core in the solid state.
