Unsymmetrical carbonates of the formula <IMAGE> [I] are prepared by the following reaction sequence <IMAGE> (1) <IMAGE> (2) <IMAGE> (3) where R and R' can each be -CH2C(NO2)3, CH2CF(NO2)2, -CH2CF2(NO2), -CH2CCl(NO2)2, -CH2CF3, -CH2CCl3, -CH2C(NO2)2CH3, or -CH2CF2CF2H, provided that R NOTEQUAL R' and wherein R'' is a lower alkyl group of from 1 to 6 carbon atoms. Also included are symmetrical 1,3-bis(halo- and nitroalkyl carbonyldioxy)-2,2-dinitropropanes of the formula <IMAGE> [VII] which are synthesis by the following reaction sequence <IMAGE> (a) <IMAGE> <IMAGE> b. <IMAGE> c. wherein R and R'' are as defined above. The carbonates of this invention are useful as energetic additives to propellants and explosive.
