2-Aza-21-carbaporphyrin

Tetraphenyl-2-aza-21-carbaporphyrin 220 was reacted with various acyl chlorides and excess triethylamine in refluxing dry benzene, and unexpected pyrrolidin-2-one-fused N-confused calix[4]phyrins 221 were isolated in 60-70% yield (Scheme 54) <20060L1137>. [Pg.28]

Inverted porphyrin or 2-aza-21-carbaporphyrin 88 also known as an NCP (Figure 3) was first isolated as a by-product of normal acid-catalyzed condensation of pyrrole and benzaldehyde (1994ACI779, 1994JA767). Latos-Grazynski and coworkers employed a Rothemund reaction between tolualdehyde and pyrrole in the presence of BF3-Et20 in DCM, followed by oxidation with 2,3,5,6-tetrachloro-p-benzoquinone (chloranil) to obtain NCP (1994ACI779). Simultaneously, Furuta and coworkers also reported... [Pg.132]

Reactivity and electronic structure of stable high-spin nickel(Il) or copper (II) derivatives of core modified porphyrins (21-heteroporphyrins and 2-aza-21-carbaporphyrin) 05CCR(249)2510. [Pg.59]

The first air-stable silver(lll) complex was reported by Furuta et al. (22) in 1999, who synthesized and characterized a silver(lll) complex with 5,10,15,20-tetraphenyl-2-aza-carbaporphyrin (nctpp) as the supporting ligand. The crystal structure shows an inequivalence in the Ag—N bonds and the Ag—C bond, which reflects the asymmetric nature of the porphyrin. Later, the same group reported another silver(lll) complex with ethoxy-5,10,15,20-tetrapentylflorophenyl-3,7-diaza-21,22-dicarbaporphyrin [(n2cp)2l as the supporting ligand (Fig. 3) (23). [Pg.5]
