Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 33100-27-5, Name is 1,4,7,10,13-Pentaoxacyclopentadecane, Recommanded Product: 33100-27-5.
The titanium(IV) complexes of 12-crown-4, 15-crown-5 and 18-crown-6 and of 1,4-dithia-7,10,13-trioxacyclopentadecane (L?) of type [TiX4(eta2-L)] (X = Cl or Br, L = 15-crown-5 or 18-crown-6; X = Br, L = 12-crown-4) and [TiCl4(L?)] have been prepared from TiX4 and the ligands in anhydrous toluene, and characterised by analysis, IR, UV-visible and 1H NMR spectroscopy. Complexes with TiI4 do not form under similar conditions. The [TiCl4(L?)] complex contains the thia-oxa-crown coordinated via sulfur to the titanium. The complexes are extremely readily hydrolysed and examples of the first two stages of the hydrolysis have been characterised by X-ray crystallography. These are the dimer [(18-crown-6)Cl3Ti(mu-O)TiCl3(18-crown-6)] which contains a single non-linear oxo-bridge linking two six-coordinate titanium centres also coordinated eta2 to 18-crown-6 and to three (mer) chlorines. The second product is the tetrameric [{TiOCl2(15-crown-5)}4] in which there is an eight-membered ring composed of alternating Ti and O, each titanium also coordinated eta2 to 15-crown-5 and two terminal (cis) chlorines.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Recommanded Product: 33100-27-5. In my other articles, you can also check out more blogs about 33100-27-5
