The facile preparation of ss-diketiminate gallium amides with general formulas of either LGa(NHR)2 (L = [HC(C(Me)N(Ar)J2]-, Ar = 2,6-iPr2C6H3; R = Et (1), iPr (2), nBu (3), Ph (4)} or LGa(NHR)Cl [R = tBu (5); Bt (6)] was accomplished by the reaction of LGaCl2 with the lithium salt of the corresponding amine in 1:2 (1-4) or 1:1 (5, 6) molar ratios. Compounds 1-6 are useful synthons for further synthesis, as the amide substituents are excellent leaving groups, and the resulting amines can be cleanly and easily removed from the reaction matrix. To demonstrate this, compounds 1 and 5 were treated with ethanol, leading to the alcoholysis products LGa(OEt)2 (8) and LGa(OEt)Cl (9), respectively. Furthermore, LGa(OH)2 can be obtained in an almost quantitative yield from the hydrolysis of compounds 1-4. Additionally, the aluminum analogue of 1 - LAl(NHEt)2 (7) - was obtained to prove that the method is also suitable for other metals. Compounds 1-9 were characterized by common spectroscopic methods, and compounds 1-8 were also characterized by X-ray singlecrystal diffraction Wiley-VCH Verlag GmbH & Co. KGaA.
