Development of a quinolinium/cobaloxime dual photocatalytic system for oxidative C-C cross-couplings via H₂ release was written by Li, Jianbin;Huang, Chia-Yu;Han, Jing-Tan;Li, Chao-Jun. And the article was included in ACS Catalysis in 2021.Application of 27104-73-0 This article mentions the following:

Designing mol. photocatalysts for potent photochem. reactivities ranks among the most challenging but rewarding endeavors in synthetic photochem. Herein, we document a quinoline-based organo-photoredox catalyst, 2,4-bis(4-methoxyphenyl)quinoline (DPQN^2,4-di-OMe), that could be assembled via the facile aldehyde-alkyne-amine (A³) couplings. Unlike the reported photocatalysts, which impart their photoreactivities as covalently linked entities, our mechanistic studies suggested a distinct proton activation mode of DPQN^2,4-di-OMe. Simply upon protonation, DPQN^2,4-di-OMe could reach a highly oxidizing excited state under visible-light irradiation (E*_1/2 = +1.96 V vs a standard calomel electrode, SCE). On this basis, the synergistic merger of DPQN^2,4-di-OMe and cobaloxime formulated an oxidative cross-coupling platform, enabling the Minisci alkylation and various C-C bond-forming reactions with a diverse pool of radical precursors in the absence of chem. oxidants. The catalytic loading of DPQN^2,4-di-OMe could be minimized to 0.025 mol % (TON = 3360), and a polymer-supported photocatalyst, DPQN^2,4-di-OR@PS, was prepared to facilitate catalyst recycling (at a 0.50 mmol % loading and up to five times without significant loss of photosynthetic efficiency). In the experiment, the researchers used many compounds, for example, Methyl isoquinoline-3-carboxylate (cas: 27104-73-0Application of 27104-73-0).

Methyl isoquinoline-3-carboxylate (cas: 27104-73-0) belongs to isoquinoline derivatives.

And the article was included in European Journal of Inorganic Chemistry in 2000.Product Details of 27104-73-0 This article mentions the following:

Two series of cyclometallated and noncyclometallated Ru(II) complexes incorporating mono- or disubstituted 1,10-phenanthroline- and 2,2′:6′,2”-terpyridine-type ligands were synthesized and characterized. An x-ray crystal structure for 1 of the complexes, Ru(ttpy)(mapH)-(Cl)(PF₆), was obtained (mapH = 2-p-anisyl-1,10-phenanthroline; ttpy = 4′-tolyl-2,2′:6′,2”-terpyridine): monoclinic, P2₁/c, a = 15.378(4), b = 13.263(3), c = 20.306(6) Å, β = 90.54(2)°, V = 4141.4 ų, Z = 4, ρ_c = 1.553 g/cm³, μ(CuKα) = 47.206 cm^-1, T = -100°, 4247 observed reflections with I > 3σ(I), 559 refined parameters, R(F) = 0.037, R_w(F) = 0.062. Distinct electrochem. and photophys. properties were observed for the 2 series: a remarkable feature is the observation of relatively long-lived MLCT excited states (from 70-106 ns at room temperature in MeCN) for 3 of the cyclometallated complexes. A discussion is given on the role of factors like sigma donation by the cyclometallating ligands, interligand steric hindrance, and interligand π-π interactions that affect the electrochem. and spectroscopic properties.

A Metal-Organic Framework as a Multiphoton Excitation Regulator for the Activation of Inert C(sp³)-H Bonds and Oxygen was written by Ji, Guanfeng;Zhao, Liang;Wei, Jianwei;Cai, Junkai;He, Cheng;Du, Zenggang;Cai, Wei;Duan, Chunying. And the article was included in Angewandte Chemie, International Edition in 2022.Safety of Methyl isoquinoline-3-carboxylate This article mentions the following:

The activation and oxidization of inert C(sp³)-H bonds into value-added chems. affords attractively economic and ecol. benefits as well as central challenge in modern chem. Inspired by the natural enzymic transformation, herein, we report a new multiphoton excitation approach to activate the inert C(sp³)-H bonds and oxygen by integrating the photoinduced electron transfer (PET), ligand-to-metal charge transfer (LMCT) and hydrogen atom transfer (HAT) events together into one metal-organic framework. The well-modified NAD (NAD⁺) mimics oxidized Ce^III-OEt moieties to generate Ce^IV-OEt chromophore and its reduced state mimics NAD^. via PET. The in situ formed Ce^IV-OEt moiety triggers a LMCT excitation to form the alkoxy radical EtO^., abstracts a hydrogen atom from the C(sp³)-H bond, accompanying the recovery of Ce^III-OEt and the formation of alkyl radicals. The formed NAD^. activates oxygen to regenerate the NAD⁺ for next recycle, wherein, the activated oxygen species interacts with the intermediates for the oxidization functionalization, paving a catalytic avenue for developing scalable and sustainable synthetic strategy. In the experiment, the researchers used many compounds, for example, Methyl isoquinoline-3-carboxylate (cas: 27104-73-0Safety of Methyl isoquinoline-3-carboxylate).

And the article was included in Journal of the American Chemical Society in 1981.Computed Properties of C11H9NO2 This article mentions the following:

The mild two electron oxidation of quinolines I [R = MeO; R¹ = H, Me, CO₂H, 3,4-(MeO)₂C₆H₃CH₂; R²-R⁴ = H] and carbolines II (R⁵ = H, Me; R⁶, R⁷ = H; R⁸ = H, CO₂Me) by Ph₂Se(OCOCF₃)₂ (III) gave the corresponding I (R³R⁴ = bond) and II (R⁶R⁷ = bond) in high yields. Iminium cations were prepared regiospecifically when I (R = MeO, H; R¹, R³ = H; R² = H, CO₂Me; R⁴ = Me) were treated with III. I (R = R¹ = R³ = R⁴ = H; R² = CO₂H, CO₂Me) were oxidatively decarboxylated by III to give the corresponding isoquinolines. The mechanistic rationale for these oxidations was discussed based on the formation of an intermediate azulene.

Direct C伪-heteroarylation of structurally diverse ethers via a mild N-hydroxysuccinimide mediated cross-dehydrogenative coupling reaction was written by Liu, Shihui;Liu, Aoxia;Zhang, Yongqiang;Wang, Wei. And the article was included in Chemical Science in 2017.Name: Methyl isoquinoline-3-carboxylate This article mentions the following:

A new, efficient, N-hydroxysuccinimide (NHS) mediated, mild and metal-free CDC strategy for the direct C伪-heteroarylation of diverse ethers such as THF, tetrahydro-2H-pyran, 1,4,7,10-tetraoxacyclododecane, etc. has been developed.
