, p. 499 - 511 (2015)
An acid-induced reaction of meso-tetraphenyl-2-hydroxyimino-3-oxoporphyrin leads, with concomitant loss of water, to a formal electrophilic aromatic substitution of the ortho-position of the phenyl group adjacent to the oxime, forming a quinoline moiety.
A porphyrin with two coordination sites: The biquinoline ligand as a new potential external chelate
Jeandon, Christophe,Ruppert, Romain
supporting information; experimental part, p. 4098 - 4102 (2011/09/14)
A highly symmetrical doubly fused porphyrin was obtained after two successive intramolecular cyclizations.1 The first supplementary ring was closed by using the Cadogan reaction, involving the generation of an intermediate nitrene from the starting nitro
Quinoline-annulated porphyrins

, p. 1322 - 1325 (2011/04/26)
Porphyrin-2,3-dione mono- and dioximes were used as starting materials for the efficient syntheses of mono- and bis-quinoline-annulated porphyrins and their corresponding N-oxides. Owing to an extended π-system, these novel porphyrinoid chromophores show
