Synthesis of a β-linked porphyrin dimer and some homo-, and hetero-bimetallic complexes
Abstract
The porphyrin boronate H2L2 undergoes Suzuki cross-coupling reaction with β-monobromoporphyrin H2L1 to give the unsymmetrically substituted porphyrin dimer H4L3 in high yield; homo-, and heter-bimetallic complexes of H4L3 are prepared.
