Facile synthesis of meso-arylamino- and alkylaminosubporphyrins.
Newcomers: meso-Arylamino- and meso-alkylaminosubporphyrins have been synthesized by the Pd-catalyzed aminations of meso-bromosubporphyrin 1 as the first example of subporphyrins containing heteroatom substituents at the meso-position. The X-ray structural analyses have revealed significant structural distortions of meso-aminosubporphyrins 2 due to the effective electronic interaction (see scheme).
