A series of mono- and bis-benzimidazolium and imidazolium salts of 4-pyrone derivatives has been synthesized in good yields, by various quaternization reactions of halomethyl derivatives of 4H-pyran-4-ones. These salts can be used as novel precursors of functionalized N-heterocyclic carbenes and some of them as novel ionic liquids.

Hexaminium salts of 4-pyrones 3a, b were synthesized by treatment of 2-(4-bromomethylphenyl)-6- methyl-4H-pyran-4-one 2a and 2-(4-bromomethylphenyl)- 6-phenyl-4H-pyran-4-one 2b with hexamethyl- enetetramine in chloroform in 71 and 84% yields respectively.
