Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 10049-08-8, Name is Ruthenium(III) chloride, Application In Synthesis of Ruthenium(III) chloride.
Tris(acetylacetonato<2-14C>)-cobalt(III), -chromium(III), -ruthenium(III), and -rhodium(III) undergo ligand exchange in acetylacetone(Hacac) at 85-190 deg C without decomposition of the complexes.The exchange rate is proportional to the complex concentration, and the first-order rate constant k0 decreases in the sequence Co(III) above Cr(III) above Ru(III) above Rh(III), k0/10-5 s-1 being 2.4 (93 deg C), 5.6 (117 deg C), 9.5 (158 deg C), and 2.4 (185 deg C), respectively.The activation enthalpies and entropies and deuterium isotope effect on k0 are significantly different between the Co(III) and the Cr(III), Ru(III) and Rh(III) complexes.An intermediate involving an one-ended acetylacetonate and a solvent molecule(Hacac) is concluded to be formed in the rate-determining step.The SN1 and the SN2 mechanism are assigned to the exchange reactions of the Co(III) complex and the others, respectively, for the rate-determining steps.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Application In Synthesis of Ruthenium(III) chloride. In my other articles, you can also check out more blogs about 10049-08-8
