Synthesis of β-octasubstituted sterically bulky porphyrins by Suzuki cross coupling
Abstract
β-Octasubstituted tetramesitylporphyrins have been prepared in good yields by Suzuki cross coupling of β-octabromotetramesitylporphyrin with aryl- and alkyl-boronic acids. A single-crystal X-ray analysis of -octamethyltetramesitylporphyrin 3a shows a saddled non-planar structure.
