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.

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).

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.

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.
