Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 1436-59-5, Name is cis-Cyclohexane-1,2-diamine, Product Details of 1436-59-5.
A series of transition-metal-containing molecular “loops” and “squares” has been prepared via a directed-assembly approach and characterized. The molecular loops were prepared from the reaction of cis-(PEt3)2Pt(OTf)2 with bis(4-pyridyl)-functionalized free-base salen-type ligands. Zn(II)-metalation of the salen-type ligands in the molecular loops converts the loops to molecular squares. Alternatively, the squares can be obtained by the directed assembly of cis-(PEt3)2Pt(OTf)2 and bis(4-pyridyl)-functionalized Zn(II)-salen-type ligands. A concentration-dependent dynamic equilibrium between cyclic species was observed when bis(3-pyridyl)-functionalized free-base salen-type ligand was employed in the reaction. Zn(II) or Cr(III) metalation of the free-base ligand shifted the equilibrium to the single dimeric species. The incorporation of multiple reactive metal sites into a single, cavity-containing supramolecular structure points toward catalytic applications for these new assemblies.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Product Details of 1436-59-5. In my other articles, you can also check out more blogs about 1436-59-5
