  • Title: Metal-free C-H amination of unactivated hydrocarbons with sulfonylimino-λ(3)-bromanes generated in situ from (diacetoxybromo)benzene.
    Author: Miyamoto K, Ota T, Hoque MM, Ochiai M.
    Journal: Org Biomol Chem; 2015 Feb 21; 13(7):2129-33. PubMed ID: 25525964.
    Abstract:
    A simple method for direct metal-free C-H amination of unactivated hydrocarbons using easy-handling diacetoxy-λ(3)-bromane and triflylamide or sulfamate esters was developed. The high 2°/3° regioselectivities and deuterium isotope effects suggest a concerted organonitrenoid transition state, analogous to C-H amination with N-triflylimino-λ(3)-bromane.
