Porphyrins. 13. Reaction of meso-dimethylaminomethyletioporphyrin I with nucleophiles in the presence of zinc acetate
- 41 Downloads
When meso-dimethylaminomethyletioporphyrin I (I) is heated in CCl4 or tetrahydrofuran (THF) in the presence of zinc acetate, it reacts with alcohols to give the corresponding meso-alkoxy-methylporphyrins. Under similar conditions CH acids (acetone, acetylacetone, nitromethane, and others) form the corresponding meso-substituted derivatives with the formation of a C-C bond. Ethers are formed when the copper and nickel complexes of I are heated in ethylene glycol.
