Abstract
The reaction of trimethylaluminum or trimethylgallium with bulky primary amines affords, in the first instance, dimeric aminoalkylalanes and gallanes via the elimination of 1 equiv of methane. Additional loss of methane may be accomplished by further heating of the aminometallanes to give either associated iminoalanes, orthometalated aminoalanes, or orthometalated aminogallanes. The aminometallane compounds (Me 2 MNHDipp) 2 (Dipp=2,6-i-Pr 2 -C 6 H 3 ; M=Al (1) or Ga (2)), [Me 2 MNH(1-Ad)] 2 (1-Ad=1-adamantyl; M=Al (3) or Ga (4)), and (Me 2 GaNHPh) 2 (5) were isolated by the treatment of MMe 3 (M=Al or Ga) with 1 equiv of the primary amine in refluxing toluene
