Compound: 2-Phenylpyridine, is researched, Molecular C11H9N, CAS is 1008-89-5, about Visible-Light-Induced ortho-Selective Migration on Pyridyl Ring: Trifluoromethylative Pyridylation of Unactivated Alkenes. Author is Jeon, Jinwon; He, Yu-Tao; Shin, Sanghoon; Hong, Sungwoo.

The photocatalyzed ortho-selective migration on a pyridyl ring has been achieved for the site-selective trifluoromethylative pyridylation of unactivated alkenes. The overall process was initiated by the selective addition of a CF3 radical to the alkene moiety of N-(alkenyloxy)pyridinium salts I [X = O, Z = (CH2)3, R1 = H, 2-Me, 3-MeO2C, 4-Ph, etc., R2 = H, Me; X = O, Z = CH2, CH2CH2, (CH2)4, R1 = 4-MeO2C, R2 = H; X = NTs, Z = CH2, CH2CH2, R1 = H, 4-MeO2C, R2 = H; etc.] to provide a nucleophilic alkyl radical intermediate, which enabled an intramol. endo addition exclusively to the ortho-position of the pyridinium salt to afford the corresponding functionalized pyridines II. Both secondary and tertiary alkyl radicals were well-suited for addition to the C2-position of pyridinium salts to ultimately provide synthetically valuable C2-fluoroalkyl functionalized pyridines. Moreover, the method was successfully applied to the reaction with P-centered radicals. The utility of this transformation was further demonstrated by the late-stage functionalization of complex bioactive mols.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Rational Design of Near-Infrared-Absorbing Pt(II)-Chelated Azadipyrromethene Dyes as a New Generation of Photosensitizers for Synergistic Phototherapy, published in 2020-12-21, which mentions a compound: 1008-89-5, mainly applied to platinum azadipyrromethene dye preparation cancer photothermal photodynamic photosensitizer, Formula: C11H9N.

Pt(II) photosensitizers are emerging as novel Pt anticancer agents for cancer photodynamic therapy (PDT) to avoid uncontrollable toxicity of cisplatin. However, the application of Pt(II) photosensitizers is limited by tumor hypoxia and the poor penetration depth of excitation light. To overcome these drawbacks, exploiting the next generation of Pt anticancer agents is of urgent need. According to theor. calculations, novel near-IR (NIR)-absorbing Pt(II)-chelated azadipyrromethene dyes (PtDP-X, where X = N, C, and S) were designed. Importantly, spin-orbit coupling of the Pt atom could promote the intersystem crossing of a singlet-to-triplet transition for converting oxygen to singlet oxygen (1O2), and the azadipyrromethene skeleton could provide a strong photothermal effect. As expected, PtDP-X exhibited intense NIR absorption and synergistic PDT and photothermal effects with low dark cytotoxicity. Furthermore, water-soluble and biocompatible PtDP-N nanoparticles (PtDP-N NPs) were prepared that achieved effective tumor cell elimination with low side effects under 730 nm light irradiation in vitro and in vivo. This pioneering work could push the exploitation of NIR-absorbing metal-chelated azadipyrromethene dyes, so as to promote the pos. evolution of phototherapy agents. A novel series of near-IR (NIR)-absorbing Pt(II)-chelated azadipyrromethene dyes (PtDP-X, where X = N, C, and S) are developed as a new generation of Pt(II)-based anticancer agents through a facile and feasible approach. Upon NIR light irradiation, PtDP-X possesses excellent synergistic photodynamic (PDT) and photothermal (PTT) therapeutic effects in vitro and in vivo.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system.

Weight loss, potentiodynamic polarization and electrochem. impedance spectroscopy (EIS) were used to investigate the corrosion inhibition of 2-(4-pyridyl)-benzimidazole (PBI) for carbon steel in hydrochloric acid. It is found that the inhibition efficiency of PBI increases with the increase of the concentration of PBI, and decreases with the increase in the temperature and concentration of hydrochloric acid. PBI is adsorbed on the surface of carbon steel spontaneously, and the adsorption of PBI obeys Langmuir isotherm.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1008-89-5, is researched, Molecular C11H9N, about Desulfonative Suzuki-Miyaura Coupling of Sulfonyl Fluorides, the main research direction is sulfonyl fluoride desulfonative Suzuki Miyaura coupling palladium; SuFEx; cross-coupling; heterocycles; palladium; reaction mechanisms.COA of Formula: C11H9N.

Sulfonyl fluorides have emerged as powerful “”click”” electrophiles to access sulfonylated derivatives Yet, they are relatively inert towards C-C bond forming transformations, notably under transition-metal catalysis. Here, authors describe conditions under which aryl sulfonyl fluorides act as electrophiles for the Pd-catalyzed Suzuki-Miyaura cross-coupling. This desulfonative cross-coupling occurs selectively in the absence of base and, unusually, even in the presence of strong acids. Divergent one-step syntheses of two analogs of bioactive compounds showcase the expanded reactivity of sulfonyl fluorides to encompass both S-Nu and C-C bond formation. Mechanistic experiments and DFT calculations suggest oxidative addition occurs at the C-S bond followed by desulfonation to form a Pd-F intermediate that facilitates transmetalation.
