A water-mediated C-H activation using sulfoxonium ylides was reported, providing a general, green and step-economic approach to construct a C-C bond and varieties of useful N-heterocycle scaffolds. Three series of aryl-alkylketones RCOCH2R1 [R = t-Bu, 1-adamantanyl, Ph; R1 = 2-(2-pyridyl)phenyl, 2-(2-pyridyl)-3-thienyl, 2-pyrazol-1-ylphenyl, etc.], benzothiazines I [R2 = Me, i-Pr, Ph, Bn; R3 = i-Pr, t-Bu, Ph; R4 = H, 6-Me, 6-OMe, 6-F, 8-OMe] and isoquinolines II [R5 = H, 8-F, 6-Br, etc.; R6 = H, Me; R7 = 2,6-di-MeOC6H3, 2-naphthyl, 2-thienyl, etc.] were synthesized via rhodium-catalyzed coupling of arenes/sulfoximines/benzylamines with sulfoxonium ylides. In the experiment, the researchers used many compounds, for example, 2-(m-Tolyl)pyridine (cas: 4373-61-9SDS of cas: 4373-61-9).
2-(m-Tolyl)pyridine (cas: 4373-61-9) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. 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. SDS of cas: 4373-61-9
