Rhodium(III)-Catalyzed Selective C-H Acetoxylation and Hydroxylation Reactions was written by Wu, Yunxiang;Zhou, Bing. And the article was included in Organic Letters in 2017.Safety of 2-(m-Tolyl)pyridine This article mentions the following:
An efficient Cp*Rh(III)-catalyzed, chelation-assisted C(sp2)-H acetoxylation and hydroxylation reaction has been developed for the first time. The reaction proceeds under mild conditions and allows for selective preparation of C-H acetoxylation and hydroxylation products, thus providing a good complement to previous C-H oxygenation reactions and expanding the field of Cp*Rh(III)-catalyzed C-H functionalizations. In the experiment, the researchers used many compounds, for example, 2-(m-Tolyl)pyridine (cas: 4373-61-9Safety of 2-(m-Tolyl)pyridine).
2-(m-Tolyl)pyridine (cas: 4373-61-9) belongs to pyridine derivatives. Pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). 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. Safety of 2-(m-Tolyl)pyridine
