Amberlyst-15®: a novel and recyclable reagent for the synthesis of 1,5-benzodiazepines in ionic liquids

Abstract

The solid acid, Amberlyst-15® immobilized in the air- and moisture-stable ionic liquid, 1-butyl-3-methylimidazolium hexafluorophosphate is found to catalyze efficiently the condensation of o-phenylenediamines with ketones under mild conditions to afford the corresponding 1,5-benzodiazepine derivatives in high yields with high selectivity.
