In 2022,Zhou, Bei; Ma, Zhuang; Alenad, Asma M.; Kreyenschulte, Carsten; Bartling, Stephan; Beller, Matthias; Jagadeesh, Rajenahally V. published an article in Green Chemistry. The title of the article was 《Cobalt-catalysed CH-alkylation of indoles with alcohols by borrowing hydrogen methodology》.Quality Control of 3-Pyridinemethanol The author mentioned the following in the article:
A general heterogeneous cobalt-catalyzed CH-alkylation of indoles with alcs. was reported. Utilizing this straightforward borrowing hydrogen methodol., a series of substituted and functionalized indoles were easily coupled with benzylic, heterocyclic, and aliphatic alcs. including methanol to prepare >65 substituted indoles in good to excellent yields. The resulting products represented an interesting class of heterocyclic compounds widely used in organic synthesis and medicinal chem. Key for this synthesis was the use of specific cobalt-nanoparticles supported on N-doped carbon, which were conveniently prepared by the pyrolysis of a templated material generated in-situ by mixing cobalt-nitrate, zinc-nitrate, 2,6-diaminopyridine, and colloidal silica, and subsequent removal of silica. In the part of experimental materials, we found many familiar compounds, such as 3-Pyridinemethanol(cas: 100-55-0Quality Control of 3-Pyridinemethanol)
3-Pyridinemethanol(cas: 100-55-0) belongs to pyridine. When pyridine is adsorbed on oxide surfaces or in porous materials, the following species are commonly observed: (i) pyridine coordinated to Lewis acid sites, (ii) pyridine H-bonded to weakly acidic hydroxyls, and (iii) protonated pyridine. At high coverage, physisorbed pyridine and protonated dimers can also be observed.Quality Control of 3-Pyridinemethanol
