Procedure

A solution of 1,4-dinitrocubane (Eaton, P.E.; et al; J. Org. Chem.; 1984, 49, 185; Eaton, P.E.; Wicks, G.E.; J. Org. Chem.; 1988, 53, 5353) in oxalyl chloride was irradiated under a sunlamp for 12 h at room temperature. After removing oxalyl chloride under reduced pressure, the reaction mixture was hydrolyzed nd partioned between ethyl acetate and 5% aqueous NaOH. From the organic phase was isolated 2-chloro-1,4-dinitrocubane, 3, and 2,5-dichloro-1,4-dinitrocubane, 4. After acidification of the alkaline layer with HCl and extraction with ethyl acetate, 2-carboxy-1,4-dinitrocubane, 5, was obtained in 68% yield. ##STR1##
