Abstract : This invention relates to energetic organic compounds and more particularly to halo and nitroalkyldichloro-formals. These dichloroformals are prepared by reacting the corresponding thionocarbonate of the formula (RCH(sub 2)O)(sub 2)C=S, wherein R is as defined above with Sulfuryl chloride in the presence of a Friedel-Craft catalyst (e.g., AlCl(sub 3) or TiCl(sub 4)). Another method is to react the thionocarbonate with chlorine gas in the presence of a polar additive such as 2.2.2-trifluoroethanol or acetonitrile. These energetic dichloroformals are useful as explosive and propellant ingredients and as intermediates in the synthesis of other energetic explosive and propellant ingredients.
