Description
O-Diphenylphosphinylhydroxylamine (DPPH) is a versatile electrophilic amination reagent that has been used widely for the amination of stable carbanions, Grignard reagents, and π-electron-rich nitrogen heterocycles. Researchers have used DPPH for the aziridination of enones. Compared to other hydroxylamine derivatives typically stored as hydrochloride salts, this activated phosphinyl reagent exhibits good stability and can be stored indefinitely at 0 ℃. This compound in a single step from hydroxylamine hydrochloride and diphenylphosphinic chloride[1].
General Description
O-(Diphenylphosphinyl)hydroxylamine is a general reagent for electrophilic C-amination, which aminates a variety of stable carbanions and Grignard reagents.
