Abstract α-monosubstituted pyridiniums were readily prepared by the one-pot reaction of their corresponding pyryliumsalts and primary amines. This result shows that such kind of pyridiniums can be prepared via this route. It was proved that the number of phenyl groups at the pyrylium ring had a crucial effect on this one-pot synthetic route. GRAPHICAL ABSTRACT
