Chemistry of Heterocyclic Compounds Aims and scope

Abstract

Derivatives of Β-alkoxy- and Β-(phenylamino)styrylpyrylium salts, the hydrolysis of which leads to phenacylpyrylium salts and 4-benzoylmethylenepyrans, are formed in the reaction of 4-phenylethynylpyrylium salts with alcohols and aromatic amines. Ethynyl-substituted pyridines and pyridinium salts were synthesized by the action of ammonium acetate and methylamine, benzylamine, and butylamine. A Β-methylaminostyryl-1-methyl-substituted pyridinium salt is formed with excess methylamine.
