The reaction sequences for preparing these branched polynitroalkyl diols can be summarized as follows: ##STR6## where Z is --C(NO2)3, --CF(NO2)2, --C(NO2)2CH3, or --N(NO2)CH3. The reaction of one mole of trinitromethane with one mole of gamma-crotonolactone under the reaction conditions of example 1 produces 4-hydroxy-3-(trinitromethyl)butyric acid, gamma-lactone which is reduced by borane-tetrahydrofuran to produce 2-(trinitromethyl)-1,4-butanediol as shown in example 3. Similarly, the reaction of one mole of fluorodinitromethane with gamma-crotonolactone under the reaction conditions of example 2 produces 4-hydroxy-3-(fluorodinitromethyl)butric acid, gamma-lactone which is reduced by borane-tetrahydrofuran to produce 2-(fluorodinitromethyl)-1,4-butanediol as shown in example 4. Using the same procedure, 1,1-dinitroethane and gamma-crotonolactone can be used to produce 2-(1,1-dinitroethyl)-1,4-butanediol and methyl nitramine and gamma-crotonolactone can be used to produce 2-(methylnitraza)-1,4-butanediol.
