Abstract
The pyrolysis of
imidazolium halides substituted on the nitrogen atoms by alkyl or aryl groups
leads to 1-substituted imidazoles. Differing substituents cleave at different
rates, while the nature of the anion and the influence of substituents at C4
modify the reaction products. Tetraphenylborate and perchlorate salts fail to
dealkylate. An SN2 (or SN2?) mechanism appears to be the
most likely for the process.
