Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 31251-41-9, Name is 8-Chloro-5,6-dihydro-11H-benzo[5,6]cyclohepta[1,2-b]pyridin-11-one, SMILES is O=C1C2=CC=C(Cl)C=C2CCC3=CC=CN=C31, belongs to pyridine-derivatives compound. In a document, author is Tabe, Hiroyasu, introduce the new discover, SDS of cas: 31251-41-9.
Creation and stabilisation of tuneable open metal sites in thiocyanato-bridged heterometallic coordination polymers to be used as heterogeneous catalysts
A series of thiocyanato-bridged heterometallic coordination polymers with a 3D reticular network have been synthesised by the reaction of [Pt-IV(SCN)(6)](2-) with M-II ions to form {M-II[Pt-IV(SCN)(6)]}(n) and {[M-II(CH3OH)(2)][Pt-IV(SCN)(6)]}(n) (M-II = Mn-II, Fe-II, Co-II, Ni-II or Cu-II) in water and methanol, respectively. Single-crystal X-ray analyses revealed the absence of open metal sites in {M-II[Pt-IV(SCN)(6)]}(n)s and the formation of potential open metal sites at the M-II ions of {[M-II(CH3OH)(2)][Pt-IV(SCN)(6)]}(n)s by the coordination of methanol. One of the two coordinating methanol molecules in {[Co-II(CH3OH)(2)][Pt-IV(SCN)(6)]}(n) was replaced with pyridine to stabilise the open metal sites, because the methanol molecules are too labile to maintain open metal sites in water. The heterogeneous catalysis of coordination polymers with and without open metal sites was examined for organophosphate hydrolysis and photocatalytic water oxidation to clarify the requisites for heterogeneous catalysts.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 31251-41-9 is helpful to your research. SDS of cas: 31251-41-9.
