Efficient carbonyl insertion into C-O and C-N bonds using [Lewis acid]-+[Co(CO)4]– complexes [Cp2Ti(thf)2][Co(CO)4] 1 and [(salph)Al(thf)2][Co(CO)4] 2 [salph = N,N’-bis(3,5-di-tert-butylsalicylidene)phenylenediamine] gives regio- and stereoselective carbonylation of a variety of epoxides and aziridines to yield 尾-lactones and 尾-lactams, resp. Both transformations are proposed to occur by the same mechanism, yielding products with inversion of configuration at the site of CO insertion. In the experiment, the researchers used many compounds, for example, Trans-2-(benzylamino)cyclohexanol (cas: 40571-86-6Quality Control of Trans-2-(benzylamino)cyclohexanol).
Trans-2-(benzylamino)cyclohexanol (cas: 40571-86-6) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R鈥昈鈭?. For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.Quality Control of Trans-2-(benzylamino)cyclohexanol
