Ionic Liquids As Solvent For Efficient Esterification Of Carboxylic Acids With Alkyl Halides, Yetki̇n Gök, Bülent Alici, Engi̇n Çeti̇nkaya, İsmai̇l Özdemi̇r, Özlem Özeroğlu
Turkish Journal of Chemistry
The selective esterification of carboxylic acid derivatives with a variety of alkyl halides was carried out using ionic liquid as solvent in the presence of triethylamine. The reaction was found to proceed under relatively mild conditions with excellent conversions (up to 99%) and selectivities. The ionic liquid was recycled and reused.

Novel 1,3-dialkylimidazolinium and 1,3- dialkyltetrahydropyrimidinium hexafluorophosphate salts as N-heterocyclic carbene precursors were prepared by reacting N,N'-dialkylethandiamine or N,N'-dialkylpropandiamine, triethyl orthoformate, and ammonium hexafluorophosphate. The salts were characterized spectroscopically and tested in homogeneous Heck reactions.
