摘要：

The treatment at boiling of 5,10,15,20-tetraphenyl-2-formylporphyrin copper(II) with saturated solution of p-chloranil in benzene in the presence of 70% aqueous trifluoroacetic acid affords alongside verdin (16.7%) its isomer with a keto group located in the P-position of the macrocycle in 71% yield.
