opening smoothly with various arylamines in 1-butyl-3-methylimidazoliumtetrafluoroborate ([bmim]BF4) or 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim]PF6) ionicliquids under mild and neutral conditions to afford the corresponding vicinal-diamines in excellent yields with high regioselectivity. The recovered activated ionicliquids are recycled for four to five runs with no loss of activity
β-Cyclodextrin catalyzed for the first time a facile ring opening of aziridines with nucleophiles such as aromatic amines and azides in water at room temperature to afford diamines and azidoamines respectively in good yields.
