Chemical Reactions and Mechanisms

The reactions of trimethylaluminum and trimethylaluminum trimethylamine with various methylhydrazines have produced a number of complexes and polymers: with methylhydrazine, both Me 3 Al and Me 3 Al:NMe 3 produce the polymer [—MeAlNHNMe—] n with 1,2-dimethylhydrazine, both produce the polymer [—Al(MeNNMe) 1.5 —] n ; with 1,1-dimethylhydrazine, Me 3 Al produces [Me 2 Al—NHNMe 2 ] 2 and Me 3 Al:NMe 3 produces the unusual complex Me 2 Al(NHNMe 2 ) (NH 2 NMe 2 ); with trimethylhydrazine, Me 3 Al produces [Me 2 Al—NMeNMe 2 ] 2 and Me 3 Al:NMe 3 produces an isomer with the same formula but an as-yet-uncharacterized structure. In addition, the intermediate Me 3 Al:NHMeNMe 2 has been isolated from the reaction of either Me 3 Al or Me 3 Al:NMe 3 with trimethylhydrazine. With tetramethylhydrazine, Me 3 Al produces Me 3 Al:NMe 2 NMe 2 . The formation of the complexes with covalent aluminum–nitrogen bonds is specific and methane is the only gas eliminated during these reactions.
