The reactions of two equivalents of LGa {L = HC[C(Me)N(2,6-iPr2C6H3)]2} with SbX3 (X = Br, I, OEt) proceed with elimination of LGaX2 and formation of Ga-substituted distibenes [L(X)GaSb]su

A series of group 13 metal complexes featuring the β-diketiminate ligand [{(C6H3-2,6-i-Pr2)NC(Me)}2CH] - (i.e., [Dipp2nacnac]-, Dipp = C6H3-2,6-i-Pr2) have been prepared and spectroscopically and structurally characterized. The chloride derivatives Dipp2nacnacMCl2 (M = Al (3), Ga (5), In (8)) were isolated in good yield by the reaction of 1 equiv of Dipp2nacnacLi·Et2O (2) and the respective metal halides. The iodide derivatives Dipp2nacnacMl2 (M = Al (4), Ga (6), In (9)), which are useful for reduction to afford M(I) species, were made by a variety of routes. Thus, 4 was obtained by treatment of the previously reported Dipp2nacnacAlMe2 with I2, whereas the gallium analogue 6 was obtained as a product of the reaction of GaI with Dipp2nacnacLi·EtzO, and 9 was obtained by direct reaction of InI3 and the lithium salt. The methyl derivatives Dipp2nacnacMMe2 (M = Ga (7), In (10)), which are analogous to the previously reported Dipp2nacnacAlMe2, were synthesized by the reaction of GaMe3 with Dipp2nacnacH (1) or by reaction of the indium chloride derivative 8 with 2 equiv of MeMgBr in diethyl ether. The compounds 3-10 exist as colorless, air- and moisture-sensitive crystalline solids. Their X-ray crystal structures feature nearly planar C3N2 arrays in the Dipp2nacnac ligand backbone with short C-C and C-N distances that are consistent with a delocalized structure. However, there are large dihedral angles between the C3N2 plane and the N2M metal coordination plane which have been attributed mainly to steric effects. The relatively short M-N distances are consistent with the coordination numbers of the metals and the normal/dative character of the nitrogen ligands. The compounds were also characterized by 1H and 13C NMR spectroscopy. 1H NMR data for 7 revealed equivalent methyl groups whereas the spectrum of 10 displayed two In-Me signals which indicated that ring wagging was slow on the 1H NMR time scale.
