    Substituent-Controlled Construction of A4b2-Hexaphyrins and A3b-Porphyrins: a Mechanistic Evaluation
    (Beilstein-institut, 2023) Cinar, Seda; Tasgin, Dilek Isik; Unaleroglu, Canan
    A substituent-dependent construction of novel A3B-porphyrins along with A4B2-hexaphyrins was realized by the reactions of N-tosylimines and meso-aryl-substituted tripyrranes in the presence of Cu(OTf)2 as the catalyst. The reaction mechanism of the presented method was studied on model reactions by electrospray-ionization time-of-flight (HRESI-TOF) mass spectral analysis in a timely manner. The analytical results indicated that the observed azafulvene-ended di- and tripyrrolic intermediates are responsible for the formation of porphyrinogen and hexaphyrinogen forms.
