Orthogonal cross-coupling through intermolecular metathesis of unstrained C(aryl)-C(aryl) single bonds was written by Zhu, Jun;Zhang, Rui;Dong, Guangbin. And the article was included in Nature Chemistry in 2021.Recommanded Product: 4373-61-9 This article mentions the following:
Ruthenium-catalyzed reversible C-C single-bond metathesis reaction that allowed redox- and pH-neutral biaryl synthesis. Assisted by directing groups, unstrained homo-biaryl compounds underwent aryl exchanges to generate cross-biaryl products, catalyzed by a well-defined air-stable ruthenium(II) complex. Functional groups reactive under typical cross-coupling reactions, such as halogen, silyl and boronate moieties, were compatible under the metathesis conditions. Mechanistic studies disclosed an intriguing ‘olefin-metathesis-like’ pathway that involved an unexpected heptacoordinated, 18-electron closed-shell intermediate. The distinct reaction mode discovered here is expected to inspire the development of more general C-C single-bond metathesis and orthogonal cross-coupling reactions. In the experiment, the researchers used many compounds, for example, 2-(m-Tolyl)pyridine (cas: 4373-61-9Recommanded Product: 4373-61-9).
2-(m-Tolyl)pyridine (cas: 4373-61-9) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of 閳?8.7 鑴?10閳? cm3璺痬ol閳?.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ璺痬ol閳? in the liquid phase and 140.4 kJ璺痬ol閳? in the gas phase. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C閳ユ弻 in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Recommanded Product: 4373-61-9
