Nucleophilic Addition of Thiol to Peripheral C=C Bonds of Tetraaryltetracyanoporphyrazine Macrocycle

摘要

An irreversible addition reaction of benzylmercaptan to the macrocycle of the cyanoarylporphyrazine family (Ar = p-MeOPh and Nph) was established for the first time. The reaction proceeds along the polarized peripheral semi-isolated double bonds of the macrocycle and takes place under mild conditions. Mass spectrometry and H-1 NMR spectroscopy confirm the composition and structure of the products.
