Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 18742-02-4, Name is 2-(2-Bromoethyl)-1,3-dioxolane, molecular formula is C5H9BrO2, belongs to copper-catalyst compound. In a document, author is May, Kathleen L., introduce the new discover, Application In Synthesis of 2-(2-Bromoethyl)-1,3-dioxolane.
Divalent cobalt and copper coordination complexes of kappa(2)-N, O-derivatives of (Z)-1-R-2-(2 ‘-oxazolin-2 ‘-yl)-eth-1-en-1-ates: Structure and reactivity patterns
The synthesis and characterisation of a small library of Co and Cu derivatives (29 examples) incorporating the (Z)-1-R-1-2-(4′,4′ R-2-2′-oxazolin-2’-yl)-eth-1-en-1-ate (1: R-1 = alkyl or aryl; R-2 = H or Me) skeleton is described. In the case where R-2 = H, solid-state stable Co(II) materials of formula Co(kappa(2)-N,O-L)(2) could, in some cases, be obtained following baseinduced deprotonation of 1 + H and treatment with hydrated CoX2 salts. These complexes display redox-induced solution decomposition behaviour giving Co(kappa(2)-N,O-1)(3) as one isolable product. Stable CuOI) complexes could only be obtained in the case of for R-1 = Ph and R-2 = H. In the case of R-2 = Me, distorted tetrahedral Co(II) compounds (also Co (kappa(2)-N,O-1)(2)) are obtained as above (twelve examples). Square planar derivatives of CuOI), of similar stoichiometry, are likewise isolated (eleven new examples). In contrast to the R-2 = H reactions, all of these latter materials were found to be air-stable in solution or the solid phase. In total, 18 complexes have been characterised by single crystal X-ray diffraction. Molecular modelling (PM6(tm) and DFT) are also used to elucidate the molecular properties of selected complexes. Only a single Co complex (R-1 = t-butyl and R-2 = Me) of the library displays reversible one-electron redox properties.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 18742-02-4. Application In Synthesis of 2-(2-Bromoethyl)-1,3-dioxolane.
