Beschreibung:
<jats:p>A substituent-dependent construction of novel A<jats:sub>3</jats:sub>B-porphyrins along with A<jats:sub>4</jats:sub>B<jats:sub>2</jats:sub>-hexaphyrins was realized by the reactions of <jats:italic>N</jats:italic>-tosylimines and <jats:italic>meso</jats:italic>-aryl-substituted tripyrranes in the presence of Cu(OTf)<jats:sub>2</jats:sub> 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.</jats:p>
