摘要: Abstract Zirconocene bis(perfluorobutanesulfonate) is air- and water-stable proved to be ionic on basis of conductivity measurements. It exhibits high catalytic efficiency for the synthesis N-heterocyclic compounds under solvent-free condition, such as benzimidazoles, benzodiazepines, dihydropyrimidinones dihydropyridines mild condition. Furthermore, it can reused without loss activity in a test five cycles. This system affords simple efficient approach compounds.
