Abstract : Developed are new synthetic strategies for the synthesis of polymethyleneimine precursors to RDX and HMX through the use of homogeneous catalysts based on ruthenium and; ruthenium and iron mixtures. These catalysts have proved effective for the oligomerization and cyclization of tertiary diaminoalkanes at temperatures and rates superior to the heterogeneous palladium black catalyzed reactions previously reported. Under somewhat different conditions, these same catalysts will cleave reform Si-N bonds. Activation of Si-N bonds has been found useful in several organic syntheses. In an effort to understand why palladium black is less effective than the homogeneous catalysts, an understanding of how Lindlar catalysts function was developed. In addition, a comprehensive picture of how other heterogeneous catalysts especially hydrodenitrogenation catalysts interact with nitrogen containing organics was developed. In unrelated studies, synthetic methods for preparing nitro-alkoxyaluminates with the objective of developing air and moisture stable high energy organometallics were explored. For beta-nitro alkoxy aluminates, air and moisture sensitivity decreases significantly with increasing numbers of beta-nitro groups.
