	abstract = {The stepwise, Wilkinson{\textquoteright}s catalyst-induced decarbonylation of [meso-tetraphenyl-2,3-diformylsecochlorinato]Ni(II) (4) to produce the monoformylated pigment [meso-tetraphenyl-2-formylsecochlorinato] (5) and [meso-tetrapheiiylchlorophinato]Ni(II) (6) is described. Thus, we have shown how to degrade one pyrrolic unit of the starting material, [meso-tetraphetiylporphyrinato]Ni(II) (2) in three steps to an aldimine linkage. The conformational changes of the porphyrinic macrocycle during the course of this degradation, as determined by comparison of the X-ray crystal structures of the compounds, are discussed. A comparative study delineates the UV-Vis spectroscopical consequences. In addition, the chemical reactivity of [meso-tetraphenylchlorophinato]Ni(II) (6) suggests the existence of an azepine-derived pyrrole-modified porphyrins (11, 12). (c) 2004 Elsevier B.V.

	abstract = {The osmium tetroxide-mediated dihydroxylation of meso-tetraphenylporphyrin leads to the formation of the vic-diol meso-tetraphenyl-2,3-vic-diol-2,3-chlorin. The corresponding Ni(II) complex was converted by lead tetraacetate into (meso-tetraphenyl-2,3-secochlorinato-2,3-dialdehyde)nickel(II) This novel pigment undergoes an almost quantitative, intramolecular double acetal formation when treated with methanol in the presence of acid to produce a porphyrinoid in which one pyrrolic unit is formally replaced by a six-membered ring. An X-ray crystal structure determination, the first for such a homoporphyrin, reveals the severely twisted conformation of its chromophore.},
