Nitrosoarenes: magnetic anisotropy, donor-acceptor bonding and host-guest chemistry
Nitrosoarenes (Ar-N=O) were first reported by Baeyer in 1874 after successful synthesis of nitrosobenzene via a diphenyl mercury reaction with nitrosyl bromide. C-nitroso compounds (R-N=O), like nitrosobenzene, fall between hydroxylamines (R-NH-OH) and nitro compounds (R-NO2) on the amine oxidation …
