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.eninfo:eu-repo/semantics/openAccessA3B-PorphyrinN-TosylimineCu(Otf)2 CatalysisHresi-Tof AnalysisArticle191832184010.3762/bjoc.19.1352-s2.0-85180096119WOS:00112001280000138090630Q2Q2
