Intra- vs inter-molecular electron transfer processes in C-N bond forming reactions. Photochemical, photophysical and theoretical study of 2 '-halo-[1,1 '-biphenyl]-2-amines

摘要

N-Arylation reaction is obtained when 2'-halo-[1,1'-biphenyl]-2-amines are irradiated in basic medium. On the basis of photochemical, photophysical experiments and computational studies we propose that carbazoles are formed by intermolecular electron transfer via S(RN)1 mechanism.
