Synthesis of (Alkynyl)phenyl Porphyrins by Palladium Catalysed Cross Coupling Reactions

Abstract

meso-para and meso-meta-(phenyltriflate)tritolyl porphyrins and the zinc complexes are coupled with alkynyl stannanes or terminal alkynes with palladium catalyst to give the meso-para and meta(m-alkynylphenyl)tritolylylkphenyl porphyrins as well as the zinc complex in good yields.
