Synthesis of Sulfonamide Derivatives of Carboranyl Porphyrins Based on 5-(4-Aminophenyl)-10,15,20-triphenylporphyrin and Mercapto Carboranes

Abstract

New carboranyl substituted sulfonamide porphyrins were synthesized in good yields by the reaction of amino group of 5-(p-aminophenyl)-10,15,20-triphenylporphyrin with carboranylsulfonyl chlorides prepared in situ by oxidative chlorination of corresponding mercapto carborane with trichloroisocyanuric acid in MeCN-H 2 O system. The reactions were carried out under mild conditions. The structure of all compounds obtained was confirmed by means of electronic, IR, 1 Н and 11 B NMR spectroscopy and mass spectrometry. Quantum-chemical studies by DFT calculations were carried out for synthesized porphyrin derivatives.
