Abstract:
A new route to 3,4-benzoquinone-substituted porphyrins is reported. In attempted nitration reactions on the copper(II) or nickel(II) complexes of 5,10,15,20-tetrakis(3,5-di-t-butyl-4-hydroxyphenyl)porphyrin using lithium nitrate in acetic anhydride-acetic acid/chloroform no nitration products could be detected with the main products being the corresponding complexes of 5,10,15,20-tetrakis(3,4-dioxo-5-t-butylcyclohexa-1,5-dienyl)porphyrin. These o-quinone-substituted porphyrins are available in reasonable yield ( 〉 50%), their synthesis is simple and they are of good solubility. The electrochemical and spectroelectrochemical properties of representative o-quinone-substituted Cu ( II ) and Ni ( II ) porphyrin derivatives are also reported.
