Abstract
The corresponding meso-methylporphyrins (in 40–50% yields) and porphyrins that contains a cyclopentane ring are formed by thermal sublimation in vacuo of meso-dimethylaminomethyletioporphyrin I and meso-dimethylaminomethyloctaethylporphyrin. When the Cu complex of meso-borinedimethylaminomethyletioporphyrin is heated at 200–210°C, it is converted, after demetallation, to meso-methyletioporphyrin in 75% yield. The UV, PMR, and mass spectra of the compounds obtained are presented.
