Porphyrins and their derivatives: XXVI. Synthesis and properties of 2-(3-butenyl)-5,10,15,20-tetraphenylporphyrin
摘要:
2-[2-(1,3-Dioxolan-2-yl)vinyl]-5,10,15,20-tetraphenylporphyrin and its copper complex were reduced into the corresponding ethyldioxolanes by diimide generated in the system hydrazine hydrate - air oxygen - pyridine. The hydrolysis of the obtained ethyldioxolanes results in the formylethyl derivatives that react with the methylenetriphenylphosphorane to form 2-(3-butenyl)-5,10,15,20-tetraphenyl porphyrin and its copper complex.

A series of 5-substituted 2-(2-phenyl-3,4-dihydro-2H-pyrazol-3-yl)porphyrins was prepared by treating with phenylhydrazine tetraphenylporphyrin derivatives containing in the beta-position fragments of beta-unsaturated ketones or aldehydes. The compounds obtained were oxidized. with o-chloranil into the corresponding pyrazolylporphyrins.
