Chemically induced dynamic nuclei polarization and free radicals in the reaction of triethylaluminum with nitrobenzene

The reaction of triethylaluminum with nitrobenzene in hydrocarbon solvents was studied by GC-MS and CIDNP techniques. Radical intermediates participat ing in a complex process of reduction and alkylation of nitrobenzene were o bserved in the reaction products (nitrobenzene radical anion, ethyl radical , and nitroxyl radical), and routes of their formation and decay were discu ssed.
