Rock ‘n’ roll with gold: Synthesis, structure, and dynamics of a (bipyridine)AuCl3 complex
Our previously reported microwave synthesis of (N-N)AuCl2 + complexes (where N-N = 2,2?-bipyridine (bpy) and sterically unencumbered bpy derivatives) was used to prepare derivatives where the bpy moiety was substituted in the 6,6?-positions. Instead of the square-planar complexes, these reactions produced neutral (N-N)AuCl3 complexes. In these, the tethered N-N ligand is bonded such that one N occupies a regular position in the square coordination plane of the Au(III) center and the other N occupies a pseudoaxial position, interacting with Au through an elongated Au-N bond, as determined by X-ray crystallography of two complexes. Variable-temperature 1H NMR spectroscopy reveals that the two sites of the N-N ligand undergo exchange on the NMR time scale. For N-N = 6,6?-Me2bpy the activation parameters were determined to be DeltaH? = 8.5 ± 0.4 kcal mol-1 and DeltaS? = 0.7 ± 2.0 cal K-1 mol -1. The dynamic behavior of (6,6?-Me2bpy)AuCl 3 was investigated by a DFT computational study, which detailed the in-plane rocking motion seen by NMR as well as decoordination of the axially bonded N with concomitant rolling of half of the bpy moiety by rotation around the central C-C bond of the bidentate ligand.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 4411-80-7 is helpful to your research. Synthetic Route of 4411-80-7
