A mild approach for a Cp*Co(III)-catalyzed C-H naphthylation of arenes by 7-oxabicyclic alkenes has been developed. In some cases, intermediate products with a 1,2-dihydronaphthalen-1-ol group have been isolated at room temperature in good yield. The catalytic reaction proceeds via C-H activation, insertion, β-oxygen elimination, protonation, and dehydration, resp. These simple protocols, featuring mild conditions and tolerance of functional groups, exhibit great potential for a variety of synthetic applications. In the experiment, the researchers used many compounds, for example, 2-(m-Tolyl)pyridine (cas: 4373-61-9Electric Literature of C12H11N).
2-(m-Tolyl)pyridine (cas: 4373-61-9) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the σ bonds. Reduced pyridines, namely tetrahydropyridines, dihydropyridines and piperidines, are found in numerous natural and synthetic compounds. The synthesis and reactivity of these compounds have often been driven by the fact many of these compounds have interesting and unique pharmacological properties. Electric Literature of C12H11N
