Extension of N-confused porphyrin by an o-xylene fragment.
[reaction: see text] A simple method of modification of N-confused porphyrin is provided by reactions of 5,10,15,20-tetraaryl-2-aza-21-carbaporphyrin with alpha,alpha'-dibromoxylene. The N-bromoxylene-substituted monomer formed in a first step of alkylation can be converted to the products with the extended structure on the N-confused pyrrole for which formation of organometallic silver(III) complexes has been shown.
