, (2008/06/13)
Unsymmetrical carbonates of the formula STR1 are prepared by the following reaction sequence STR2 where R and R' can each be --CH2 C(NO2)3, CH2 CF(NO..2)2, --CH2 CF2 (NO2), --CH2 CCl(NO2)2, --CH2 CF3, --CH2 CCl3, --CH2 C(NO2)2 CH3, or --CH2 CF2 CF2 H, 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 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.
