A method of preparing dichloroformals of the formula (RCH2O)2CCl2 by reaction of one mole of a thionocarbonate of the formula (RCH2O)2C=S with two moles of benzenesulfenyl chloride, chlorobenzenesulfenyl chloride, or methanesulfenyl chloride wherein R is -C(NO2)3, -CF(NO2)2, -CF2(NO2), -CCl(NO2)2, -C(NO2)2CH3, -CCl3, -CF3, or -CF2CF3. These energetic dichloroformals are useful as explosive and propellant ingredients and as intermediates in the synthesis of other energetic explosive and propellant ingredients.
