Abstract
meso-Tetraphenylporphyrins and meso-tetraphenylmetalloporphyrins were converted into stable 2,3-vic-dihydroxy-meso-tetraphenylchlorins and 2 ,3-vic-dihydroxy-meso-tetraphenylmetallochlorins by oxidation with sto ichiometric amounts of OsO4 and subsequent reduction of the isolable o smate esters. The stable dihydroxychlorins were dehydrated under acid catalysis to yield 2-hydroxy-meso-tetraphenylporphyrins.
