Abstract
The present invention describes a novel heavy-metal-free sequence leading to a superior, more economical, and scalable process for the high efficiency conversion of hexaallylhexaazaisowurtzitane (HAllylIW) to hexanitrohexaazaisowurtzitane (CL-20). The process of the present invention avoids both the preparation of benzyl chloride, which uses elemental chlorine, and catalytic hydrogenolysis steps that require palladium metal/compounds. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope of the claims.
