Alkyl radicals react with 9-nitroanthracene to give the nitro-substituted ?-complex intermediate (III) derived from addition at the 10-position.This radical does not rearomatize, but gives rise to rearrangement of the nitro-group which eventually leads to the formation of alkylanthrones.However, in the presence of stabilized radicals, intermediate (III) is trapped to give products of addition at the 9- and 10-positions.In some cases these latter products can suffer hydrogen abstraction, followed by elimination of the NO2* radical, to afford 9,10-dialkylanthracenes.
