PODAND-PORPHYRINS WITH PERIPHERAL CHELATES

Article abstract of DOI:10.1007/BF00480833

Alkylation of 5-(3'-nitro-4'-hydroxyphenyl)-10,15,20-triphenylporphyrin with chloropyridines<2,6-dichloromethyl- and 2-chloromethyl-6-(2'-nitrophenoxymethylpyridine)> as well as condensation by a mixed-aldehyde method starting with formylpyridines <2-(2'-nitro-4'-formylphenoxymethyl)-6-(2'-nitrophenoxymethyl-) or 2,6-di(2'-nitro-4'-formylphenoxymethyl)pyridine>, benzaldehyde, and pyrrole are used to synthesize previously unknown podand-porphyrins containing from one to four peripheral chelates.
