of porphyrinogen and hexaphyrinogen forms.
Keywords: A4B2-hexaphyrin; A3B-porphyrin; N-tosylimine; Cu(OTf)2 catalysis; HRESI–TOFanalysis; Introduction
Porphyrins and expanded porphyrins have found widespread applications in supramolecular chemistry [1][2][3][4]. Expanded porphyrins are utilized as
predominately observed (Figure S48 in Supporting Information File 1).
According to high-resolution electrospray-ionization time-of-flight (HRESI–TOF) analysis, at the beginning of the reaction, mass peaks of intermediates II and IV arose as a result of tripyrrane 1 addition to N-tosylimine 2d. Further
