8-Mercaptoquinoline as a Ligand for Enhancing the Photocatalytic Activity of Pt(II) Coordination Complexes: Reactions and Mechanistic Insights

A family of quinoline-platinum(II) complexes as efficient photocatalysts is presented. Their key characteristic is their easy preparation by coordination of the readily available 8-hydroxy- or 8-thio-quinoline ligands, which are well known for their strong chelating ability to different metal ions. In the different photochemical transformations investigated, such as cross-dehydrogenative coupling, oxidation of arylboronic acids, and asymmetric alkylation of aldehydes, 8-mercaptoquinoline-Pt(II) complex proved to be the most general catalyst. Moreover, quenching experiments showed that, contrary to related methods reported in the literature, these complexes followed an oxidative quenching mechanism in all transformations studied. Besides, simulations performed with high-level ab initio methods of the complexes have helped to understand their photocatalytic activity.

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 3340-78-1 is helpful to your research. Reference of 3340-78-1

Mixed-Ligand Metal-Organic Framework for Two-Photon Responsive Photocatalytic C-N and C-C Coupling Reactions

A multiple-photon photochemical process breaks the existing energy limitation of visible-light photocatalysis. Through careful incorporation of both bis(3,5-dicarboxyphenyl)pyridine and bis(3,5-dicarboxyphenyl)methylpyridinium ligands into a single metal-organic framework (MOF), we report herein photocatalytic C-N and C-C oxidative coupling reactions that evidenced the direct two-photon response process. Time-dependent luminescence-decay studies demonstrated that the framework reached the same excited state by a two-photon absorption process as that reached via a single-photon absorption process, and the excited state could activate substrates even under NIR-light irradiation. Under 660 nm light-emitting diode (LED) irradiation, both the photooxidative C-N coupling reaction of benzylamine to form benzylidene-1-phenylmethanamine and the C-C coupling reaction between nitromethane and N-phenyltetrahydroisoquinoline were accelerated directly in a heterogeneous manner. Control experiments suggested that minimal byproducts were formed under the NIR-light irradiation compared to those of the UV light catalytic reactions. Importantly, photon intensity-dependent studies exhibited a nonlinear correlation between catalytic efficiency of multivariate MOFs (MTV-MOFs) and photon power intensity, verifying the two-photon responsive nature, which indicated that metal-organic framework with high density and ordered photoactive motifs could enhance the two-photon absorption ability, thereby improving photocatalytic efficiency even under LED irradiation.

Genetic Engineering of an Artificial Metalloenzyme for Transfer Hydrogenation of a Self-Immolative Substrate in Escherichia coli’s Periplasm

Artificial metalloenzymes (ArMs), which combine an abiotic metal cofactor with a protein scaffold, catalyze various synthetically useful transformations. To complement the natural enzymes’ repertoire, effective optimization protocols to improve ArM’s performance are required. Here we report on our efforts to optimize the activity of an artificial transfer hydrogenase (ATHase) using Escherichia coli whole cells. For this purpose, we rely on a self-immolative quinolinium substrate which, upon reduction, releases fluorescent umbelliferone, thus allowing efficient screening. Introduction of a loop in the immediate proximity of the Ir-cofactor afforded an ArM with up to 5-fold increase in transfer hydrogenation activity compared to the wild-type ATHase using purified mutants.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 118864-75-8, and how the biochemistry of the body works.Safety of (S)-1-Phenyl-1,2,3,4-tetrahydroisoquinoline

alpha-Functionalization of tetrahydroisoquinolines with activated alkyl bromide under photoredox catalysis

Benzylic C-H functionalization of N-aryl-tetrahydroisoquinolines (THIQs) with various benzyl bromides was developed using a photoredox iridium (Ir) catalyst under blue LED irradiation, affording arylmethyl group-substituted THIQs in moderate to good yields (up to 82%). This photoredox catalyst-mediated reaction was also applicable to other activated bromides, including allyl bromide, cinnamyl bromide, propargyl bromide, and alpha-bromoacetate. We propose that photoredox catalyst-mediated electron transfer generates a radical species from the THIQ and another radical from the bromide, and then radical-radical cross-coupling occurs to form a new carbon-carbon bond.

Graphene-supported RuO2 nanoparticles for efficient aerobic cross-dehydrogenative coupling reaction in water

A cross-dehydrogenative coupling (CDC) reaction between tertiary amines and nitroalkanes has been realized under an oxygen atmosphere in water simply by using graphene-supported RuO2 as the catalyst, which was made from water-soluble graphene with sulfonic groups and RuCl3·nH 2O to form RuO2·nH2O nanocomposites in situ. In contrast to RuCl3·nH2O and RuO 2·nH2O, the graphene-supported RuO2 nanoparticles exhibited higher activity and stability for the aerobic CDC reaction in water.

Visible-Light-Mediated Photocatalytic Aerobic Dehydrogenation of N-heterocycles by Surface-Grafted TiO2 and 4-amino-TEMPO

Herein, the visible-light-induced dehydrogenation of N-heterocycles such as tetrahydroquinolines, tetrahydroisoquinolines, and indolines in O2-containing suspensions of a commercially available titanium dioxide photocatalyst yielding the corresponding heteroarenes is presented. 4-Amino-2,2,6,6-tetramethylpipiridinyloxyl (4-amino-TEMPO) was found to exhibit a beneficial role, as it increased the yield and improved the selectivity of the dehydrogenation reaction. Both the selectivity and the yield are further enhanced by grafting 0.1 wt % of Ni(II) ions onto the TiO2 surface. It is proposed that the basic reactant adsorbs at Lewis acid sites present at the TiO2 surface. The dehydrogenation reaction is initiated by visible-light excitation of the resulting surface complex and a subsequent single-electron transfer from the excited N-heterocycle via the conduction band of TiO2 to O2. Ni(II) ions possibly serve as an electron transfer bridge between the conduction band of TiO2 and O2, while the TEMPO derivative is assumed to act as a selective redox mediator involved in reactions of the generated reactive oxygen species.
