In tandem with Turbo Grignard (Aldrich product 656984) and an electrophilic trap, 2,3-Dibromo-propylamine hydrobromide generates a "spring loaded" electrophile, which is a convenient reagent for the installation of azetidine to secondary amines. This product is one of several synthetic useful reagents reported by Baran and coworkers on Strain-release amination.
