Unsymmetrical carbonates of the formula ##STR1## are prepared by the following reaction sequence ##STR2## where R and R' can each be --CH.sub.2 C(NO.sub.2).sub.3, CH.sub.2 CF(NO..2).sub.2, --CH.sub.2 CF.sub.2 (NO.sub.2), --CH.sub.2 CCl(NO.sub.2).sub.2, --CH.sub.2 CF.sub.3, --CH.sub.2 CCl.sub.3, --CH.sub.2 C(NO.sub.2).sub.2 CH.sub.3, or --CH.sub.2 CF.sub.2 CF.sub.2 H, provided that R.noteq.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 ##STR3## which are synthesis by the following reaction sequence ##STR4## wherein R and R" are as defined above. The carbonates of this invention are useful as energetic additives to propellants and explosive.
