Rhenium(I)-Catalyzed ortho-C-H Addition to Bicyclic Alkenes was written by Prakash, Sekar;Chang, Yu-Che;Cheng, Chien-Hong. And the article was included in Chemistry – An Asian Journal in 2018.COA of Formula: C12H11N This article mentions the following:
Hydroarylation of bicyclic alkenes was developed using a low-valent ReI-catalyzed, directing group-assisted C-H bond activation strategy. The addition of sodium acetate significantly improves the reaction efficiency; moreover, bicyclic alkenes such as 7-oxa and aza benzonorbornadienes worked efficiently under this reaction condition. Preliminary mechanistic studies suggest that, after the alkene insertion, the rhenacycle preferentially undergoes protonolysis rather than reductive elimination. In the experiment, the researchers used many compounds, for example, 2-(m-Tolyl)pyridine (cas: 4373-61-9COA of Formula: C12H11N).
2-(m-Tolyl)pyridine (cas: 4373-61-9) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.COA of Formula: C12H11N
