Abstract

1-Alkyl-n-cyanopyridinium and 1-alkyl-n-(trifluoromethyl) pyridinium salts have been synthesised and characterised in order to compare the effects of different electron- withdrawing functional groups on their ability to form ionic liquids. The presence of the electron-withdrawing nitrile or trifluoromethyl substituent on the pyridinium ring leads to salts with higher melting points than with the corresponding 1-alkylpyridinium or 1- ...
