Unprecedented aryl-to-aryl 1,5-rhodium migration is involved in decyanative silylation of aryl cyanides bearing a tethered arene. The 1,5-migration proceeds through remote C-H bond activation. 1,5-Migration also occurs in other rhodium-catalyzed reactions, including borylation and oxidative Mizoroki-Heck reactions. In the experiment, the researchers used many compounds, for example, (3,4,5-Trifluorophenyl)methanol (cas: 220227-37-2Quality Control of (3,4,5-Trifluorophenyl)methanol).
(3,4,5-Trifluorophenyl)methanol (cas: 220227-37-2) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Quality Control of (3,4,5-Trifluorophenyl)methanol
