Taking Advantage of Hg−C Bonds: Synthesis of the First Homoleptic Bis-β-diketiminate Complex Bound through the γ-Carbons
摘要:
The most common beta-diketiminate ligand, [{N(2,6-(Pr2C6H3)-Pr-i)C(Me)}(2)CH](-) (BDI), was used to synthesize a new mercury complex in which two BDI ligands are bound to the metal through the gamma-carbons in the solid state. In solution, one of the BDI ligands switches to an N,N'-binding mode; this complex is in equilibrium with the homoleptic species. The thermodynamic parameters, Delta H degrees (-2.52 kcal mol(-1)), Delta S degrees (-9.24 cal mol(-1) K-1), and Delta G degrees(298) (0.23 kcal mol(-1)), were measured using variable-temperature H-1 NMR spectroscopy.
