| Abstract
| - A straightforward synthesis toward 2-fluorinated aziridineswas developed via ring closure of β-fluorinated β-chloroamines, which were obtained via reduction of the corresponding α-fluorinated amides by borane. When 1-benzyl-2-fluoroaziridine was treated with methanol, reaction occurredat the 2-position, giving rise to N-benzyl-2,2-dimethoxyethylamine, while in the case of 1-benzyl-2,2-difluoroaziridine the 3-position was attacked, giving rise to N-benzyl-2-methoxyacetamide. These reactions point to the divergentreactive behavior of monofluoro- and difluoroaziridines.
