The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. Recommanded Product: (2R,3R,4R,5R)-2-Amino-3,4,5,6-tetrahydroxyhexanal hydrochloride, 1772-03-8, Name is (2R,3R,4R,5R)-2-Amino-3,4,5,6-tetrahydroxyhexanal hydrochloride, SMILES is O=C[C@H](N)[C@@H](O)[C@@H](O)[C@H](O)CO.[H]Cl, in an article , author is Goswami, Bhupendra, once mentioned of 1772-03-8.
The synthesis of calcium complexes ligated by three different chiral iminophosphonamide ligands, L-H (L=[Ph2P{N(R)CH(CH3)Ph}(2)]), L ‘-H (L ‘=[Ph2P{NDipp}{N(R)CH(CH3)Ph}]), (Dipp=2,6-(Pr2C6H3)-Pr-i), and L ”-H (L ”=[Ph2P{N(R)CH(CH3)naph}(2)]), (naph=naphthyl) is presented. The resulting structures [L2Ca], [L ‘ Ca-2], and [L ” Ca-2] represent the first examples of enantiopure homoleptic calcium complexes based on this type of ligands. The calcium complexes show blue-green photoluminescence (PL) in the solid state, which is especially bright at low temperatures. Whereas the emission of [L ” Ca-2] is assigned to the fluorescence of naphthyl groups, the PL of [L2Ca] and [L ‘ Ca-2] is contributed by long-lived phosphorescence and thermally activated delayed fluorescence (TADF), with a strong variation of the PL lifetimes over the temperature range of 5-295 K. Furthermore, an excellent catalytic activity was found for these complexes in hydroboration of ketones at room temperature, although no enantioselectivity was achieved.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 1772-03-8, you can contact me at any time and look forward to more communication.
