Martin Gosmann,Burchard Franck +1 more
TL;DR: Synthese d'une porphyrine avec insertion de 4 groupes vinyl a partir de [diethyl-3,4 methyl-1 pyrrolyl-2]-3 propene-2ol-1; etude du courant de cycle as mentioned in this paper.
Journal ArticleDOI
New porphyrinoids, 9. Synthesis of a bisvinylogous porphyrin with a [22] annulene system
TL;DR: The twofold vinylogously enlarged porphyrin with a 22π-electron system 3 was prepared by vinylogous bisformylation of the dipyrrylmethane 7 to give 8 and subsequent acid-catalyzed condensation of 8 with 7 as mentioned in this paper.
Journal ArticleDOI
Novel porphyrinoids, 15. Syntheses of novel expanded [26]porphyrins with conformational control by the “helical effect”
TL;DR: The aromaticity of the [26]porphyrins[2]30–33, obtained by dehydrogenation of the porphyrinogens, is evident from the 1H-NMR spectra displaying 25-ppm shift differences for the inner and outer protons of theporphyrins.
