respectively, in the presence of a 1,3-bis-<i>tert-</i>butylimidazol-2-ylidene (N-heterocyclic carbene)
as acceptor for the HCl lead to unique species of composition LGa(NH<sub>2</sub>)<sub>2</sub> and LGa(OH)<sub>2</sub> in
high yields under mild conditions. LGa(NH<sub>2</sub>)<sub>2</sub> is the first known monomeric diamide of
gallium.
