Organic reactions in ionic liquids: Ionic liquid-accelerated one-pot synthesis of 2-arylimidazo[1,2-a]pyrimidines
Xie, Yuan-Yuan
, p. 1741 - 1746 (2005)
The room-temperature ionic liquid n-butylpyridinium tetrafluoroborate (BPyBF4) is used as a recyclable alternative to classical molecular solvents in the one-pot synthesis of 2-arylimidazo[1,2-a]pyrimidines by reaction with ketones, [hydroxy(tosyloxy)iodo]benzene, and 2-aminopyrimidine. Significant rate enhancements and improved yields have been observed. Copyright Taylor & Francis, Inc.

PEG-400[poly(ethylene glycol-400)] is used as a "green" recyclable solvent in the one-pot synthesis of 2-arylimidazo[1,2-a]pyrimidines by reaction with ketones, [hydroxyl(2,4-dinitrobenzenesulfonyloxy)-iodo]benzene (HDNIB), and 2-aminopyrimidine. Signific
