Radical addition of various xanthates to N,N'-diacylimidazol-2-one occurs readily to give protected 1,2-diamines. The imide group stabilizes the adduct radical sufficiently to enable a second addition to unactivated alkenes. In some cases, the addition product could be converted into an indoline, a tetralone, or further added to an indole. Regioselective removal of one acyl group could also be accomplished.

A series of new nitramines have been synthesized. All of the new compounds possess four nitramine moieties arranged about a cyclobutane ring in a 1 alpha,2 alpha,3 beta,4 beta (cis,trans,cis) configuration. One of the new materials, 1, is unusually thermally and hydrolytically stable but sensitive to impact. 1,2,3,4-Cyclobutanetetranitramine (3) is reported for the first time.
