Abstract:

Several new cyclopropenes were synthesized and evaluated as new High Energy Density Material HEDM candidates. An optimized synthetic route to 1.1.1 propellane was developed and several bicyclo1.1.1pentanes were prepared and evaluated as HEDM materials. Preliminary work toward the preparation and study of bicyclo1.1.1pentyl carbenes under inert gas matrix isolation conditions was undertaken. Several new prismane derivatives were prepared and their stuctures determined by X-ray crystallography.
