The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 2,6-Dimethyl-3,5-heptanedione(SMILESS: CC(C)C(CC(C(C)C)=O)=O,cas:18362-64-6) is researched.Recommanded Product: 7651-82-3. The article 《Direct measurement of enantiomerization of labile aluminum(III) β-diketonates》 in relation to this compound, is published in Journal of the Chemical Society [Section] D: Chemical Communications. Let’s take a look at the latest research on this compound (cas:18362-64-6).
Dynamic NMR studies of the hexaccordinate Al complexes, tris-(2,6-dimethylheptane-3,5-dionato)aluminum(III) (AlL3) and bis(pentane-2,4-dionato)(2,6-dimethylheptane-3,5-dionato)-aluminum(III) (AlL2’L), indicate rapid enantiomerization of these complexes. In all solvents studied at room temperature, the spin-coupled doublet of the iso-Pr group of the free ligand LH appeared as a quartet in AlL3. Splitting of the doublet is due to total mol. dissymmetry centered at the Al. On heating, the quartet coalesced to a doublet (120° in chlorobenzene). Activation energy of enantiomerization 14.7 kcal/mole and free energy of activation at the coalescence temperature 21.8 kcal/mole were unchanged on reducing concentration of AlL3. The reaction is unimol. In AlL’2L, enantiomerization occurs simultaneously with L’-methyl exchange; activation energy of enantiomerization is lower than that of Me exchange (∼18 kcal/mole) by a factor of 2.
There is still a lot of research devoted to this compound(SMILES：CC(C)C(CC(C(C)C)=O)=O)Related Products of 18362-64-6, and with the development of science, more effects of this compound(18362-64-6) can be discovered.
