Efficient Synthesis and Coupling Reactions of (2-Ethynyl-5,10,15,20-tetraphenylporphyrinato)zinc(II)

All articles of this category The title compound 3 was obtained in good yield by a two step synthesis starting from 2-formyl-5,10,15,20-tetraphenylporphyrin ( 1 ). Palladium-catalyzed coupling reactions of the alkyne moiety with iodoarenes proceed well, rendering 3 a suitable building block for the synthesis of photoactive oligoporphyrin arrays. porphyrins - alkynes - Corey-Fuchs reaction - palladium-catalyzed coupling - light harvesting systems
