Chemistry, like all the natural sciences, begins with the direct observation of nature¡ª in this case, of matter.120013-39-0, Name is 5,6-Dimethoxy-2-(4-piperidinylmethyl)-1-indanone hydrochloride, SMILES is Cl.COC2=C(C=C1C(C(CC1=C2)CC3CCNCC3)=O)OC, belongs to piperidines compound. In a document, author is Sato, Shunsuke, introduce the new discover, Application In Synthesis of 5,6-Dimethoxy-2-(4-piperidinylmethyl)-1-indanone hydrochloride.
[Ir(tpy)(bpy)Cl] as a Photocatalyst for CO2 Reduction under Visible-Light Irradiation
Mononuclear iridium(III) terpyridine (tpy) 2,2-bipyridine (bpy) [Ir(tpy)(bpy)Cl](2+) photocatalysts (denoted [Ir(bpy)]) were developed for selective CO2 reduction to HCOOH under visible light. The CO2 reduction product could be changed dramatically by substituting a 2-phenylpyridine (ppy) ligand with bpy, with the mononuclear Ir ppy complex ([Ir(tpy)(ppy)Cl](+)) acting as a photocatalyst for selective CO2 reduction to CO. A mechanistic study showed a structural change in [Ir(bpy)] during the photocatalytic reaction. The [Ir(bpy)] complex was transformed into an iridium-hydride complex ([Ir(tpy)(bpy)H](2+)) during an early stage of the photocatalytic reaction. However, [Ir(tpy)(bpy)H](2+) did not function as a key intermediate in the photochemical CO2 reduction because an additional structural change occurred. The tpy ligand of the Ir complex was reduced to piperidine-2,6-di-2-pyridine ligand during the photocatalytic reaction, resulting in the production of [Ir(piperidine-2,6-di-2-pyridine)(bpy)H](2+), which was the actual photocatalyst for HCOOH production.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.
