摘要: A simple method for direct metal-free C–H amination of unactivated hydrocarbons using easy-handling diacetoxy-λ3-bromane and triflylamide or sulfamate esters was developed. The high 2°/3° regioselectivities deuterium isotope effects suggest a concerted organonitrenoid transition state, analogous to with N-triflylimino-λ3-bromane.
