The synthesis of six unsymmetrically substituted tetraarylporphyrins is reported. The compounds prepared are 5‐(R),10,15,20‐tritolylporphyrins, where R = 2‐pyridyl, 3‐pyridyl, 4‐acet‐amido, and 2,3 or 4‐hydroxyphenyl. Four new tetrasubstituted tetraarylporphyrins (5,10,15,20‐tetra‐(R)‐porphyrin) are also reported, where R = 3‐pyridyl, 4‐acetylphenyl, 4‐hydroxyphenyl and 4‐butoxyphenyl. The proton nmr spectra of these porphyrins are presented.
