Abstract

A method is proposed for the synthesis of 2,6-diphenyl-substituted pyrylium salts and 7-hydroxy-4-ethoxychromylium salts with various anions on the basis of the condensation of ethyl orthoformate with aliphatic-aromatic ketones in the presence of acid catalysts (hydrogen chloride, hydrogen bromide, hydrogen iodide, and 92% sulfuric acid) and Lewis acids (aluminum chloride, ferric chloride, and stannic chloride).
