资源简介：
The
highly sterically encumbered chelating β-diketiminate ligand,
[HC{C(Me)N(2,6-CHPh2-4-MeC6H2)}2]−, ArL–, has
been used to prepare a series of heteroleptic three-coordinate magnesium
complexes. Both the bis(imine) and imine-enamine tautomers of the
ligand precursor, ArLH, as well as the diethyl ether adduct
of the bromide complex [ArLMgBr(OEt2)], the
monomeric methyl complex [ArLMgMe], the THF-solvated and
unsolvated n-butylmagnesium complexes [ArLMgnBu(THF)] and [ArLMgnBu], and the 1-hexynyl analogue [ArLMgCCnBu] have been crystallographically
characterized. Both n-butylmagnesium complexes showed
remarkable stability in air, both in the solid state and in solution.
Single crystals of the highly sensitive magnesium hydride, [ArLMgH], underwent partial hydrolysis by solid-state water diffusion
to the isostructural hydroxide compound [ArLMgOH].
