Synthesis of aromatic diamines via trimethylsilyl-protecting aniline intermediates. Author is Pratt, J. Richard; Massey, W. Dale; Pinkerton, Frank H.; Thames, Shelby F..
A synthetic approach utilizing a Me3Si protecting group was used to produce Si and diketo containing diamines. Thus, the halogen-metal interchange of N,N-bis(trimethylsilyl)bromoanilines with BuLi in ether produced Li derivatives, which were treated with dichloro silanes or dinitriles to afford the N,N-bis(trimethylsilyl)silicon containing dianilines or the corresponding lithioimines, resp. Hydrolysis removed the trimethylsilyl protecting groups and converted the lithioimines to the carbonyl compounds to afford the free diamines.
