Secondary or tertiary nitro compounds can be easily obtained by photostimulated reaction of the anions corresponding to primary or secondary nitroalkanes with either 1-iodoadamantane (1-AdI) or ethylmercury chloride (EtHgCl) by the SRN1 mechanism. Only 1-AdI requires the presence of the enolate anion of acetone as an entrainment reagent. The procedure works well with the nitroanions derived from 1-nitropentane
