Dimers are a girl's best friend : The oxidative fusion reaction of β‐aminoporphyrins with 2,3‐dichloro‐5,6‐dicyano‐1,4‐benzoquinone (DDQ) under high‐dilution conditions furnishes pyrazine‐fused diporphyrins 1 in high yields. In a further application of the reaction, the oxidation of a 5,10,15,20‐tetraphenylporphyrin derivative provides a singly linked diaminodiporphyrin 2 along with the pyrazine‐fused diporphyrin (see scheme; only core structures are shown).
