However, tetramethylhydrazine was not detected as a product in our study. We assume that the formation of a hydrazine from the reductive coupling of two amido ligands in the TDMAA molecule is hindered when NH3 is introduced into the reaction mixture. Instead, the presence of NH3 promotes the reductive elimination by hydrogenation of the dimethylamido ligands , leading to the production of the corresponding amine, which in this case is DMA. This phenomenon can be explained by NH3 acting as a competing reactant or coordinator in the reaction system. NH3 may interact with the Al metal center or the ligands, altering the reaction pathway and favoring the hydrogenation process over the reductive coupling to form hydrazine. As a result, the formation of hydrazine is suppressed, and more dimethylamine is produced due to the increased hydrogenation of the amido ligands. In a way, the presence of NH3 influences the reaction selectivity by shifting the equilibrium towards the hydrogenation pathway, thereby affecting the overall product distribution in the decomposition and reactivity of TDMAA.
