Abstract

The room temperature ionic liquid 1-n-butyl-3-methylimidazolium tetrafluoroborate (BMImBF4), is used as a `green` recyclable alternative to classical molecular solvents for the cyclocondensation of a-bromoketones with 2-aminopyridine to form 2-arylimidazo[1,2-a]pyridines with rate accelerations and improved yields.
