Unsymmetrical carbonates of the formula [Figure][I] are prepared by the following reaction sequence [Figure] (1) [Figure] (2) [Figure] (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≠R′and wherein
Unsymmetrical carbonates of the formula [Figure][I] are prepared by the following reaction sequence [Figure] (1) [Figure] (2) [Figure] (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≠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 [Figure][VII] which are synthesis by the following reaction sequence [Figure](a) [Figure] [Figure] [Figure] b. [Figure] c. wherein R and R″are as defined above. The carbonates of this invention are useful as energetic additives to propellants and explosive.
