Rh(III)-Catalyzed Direct ortho-Chalcogenation of Phenols and Anilines was written by Yang, Shiping;Feng, Boya;Yang, Yudong. And the article was included in Journal of Organic Chemistry in 2017.Formula: C11H9NO This article mentions the following:
Aryl pyridinyl ethers and amines such as I (R = H; X = O, NH) underwent chemoselective and regioselective directed monosulfenylation with disulfides R1SSR1 (R1 = 4-MeC6H4, Ph, 4-MeOC6H4, 2-MeOC6H4, 4-ClC6H4, 4-BrC6H4, 2-BrC6H4, 2,4-Cl2C6H3, 2-naphthyl, PhCH2) and di-Me disulfide in the presence of (Cp*RhCl2)2 and AgOTf mediated by Ag2CO3 under air to yield pyridinyloxy- and pyridinylamino-substituted aryl thioethers such as I (R = R1S; R1 = 4-MeC6H4, Ph, 4-MeOC6H4, 2-MeOC6H4, 4-ClC6H4, 4-BrC6H4, 2-BrC6H4, 2,4-Cl2C6H3, 2-naphthyl, PhCH2, Me; X = O, NH) in 42-99% yields. A diaryl selenide was prepared using di-Ph diselenide,. The pyridinyl moiety was cleavage with Me triflate and either sodium methoxy or hydrazine hydrate to yield phenols and aryl amines. In the experiment, the researchers used many compounds, for example, 2-Phenoxypyridine (cas: 4783-68-0Formula: C11H9NO).
2-Phenoxypyridine (cas: 4783-68-0) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of −48.7 × 10−6 cm3·mol−1.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ·mol−1 in the liquid phase and 140.4 kJ·mol−1 in the gas phase. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Formula: C11H9NO
