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.
