Mild preparative conditions are described for the reaction of primary alkyl-, secondary alkyl-, and aryl-primary amines (including weakly basic amines) with pyryliums (including those with bulky α-substituents).Conditions were optimized by 13C n.m.r. stud
A C-13 study of the reaction of 2,4,6-triarylpyrylium cations with amines

, p. 1643 - 1647 (2007/10/02)
The reaction of primary and secondary amines with 2,4,6-triarylpyryliums is shown by C-13 NMR to proceed by fast ring opening to a vinylogous amide; in the case of primary amines this closes slowly to a pyridinium salt. The reaction in DMSO gives the pyridinium salt quantitatively when 2 moles of amines are used, with less amine significant quantities of a diketone intermediate are produced which results in slower conversion.
