Selective double functionalization of meso-tetraphenylporphyrin complexes on the same pyrrole unit by tandem electrophilic/nucleophilic aromatic substitution

Ostrowski, Stanislaw,Raczko, Anna M.

, p. 974 - 978 (2007/10/03)

The mono-nitrated meso-tetraphenylporphyrin (TPP) complex 2 could be readily functionalized on the substituted pyrrole ring with yields of up to 83%. These transformations were achieved via aromatic substitution with carbanions generated from diverse func
