And the article was included in Applied Organometallic Chemistry in 2020.Application of 40571-86-6 This article mentions the following:
Reactions of the ligand precursors 2-(2′-pyridyl)-3,5-Me2-pyrrole (L1H) and 2-(2-pyridyl)-3,4,5-Me3-pyrrole (L2H) with [(Me3Si)2N]3RE(μ-Cl)Li(THF)3 in toluene afforded low-coordinated rare-earth metal bis-amido complexes L1RE[N(SiMe3)2]2 [RE = Y(1a), Dy(1b), Er(1c), Yb(1d)] and L2RE[N(SiMe3)2]2 [RE = Y(2a), Dy(2b), Er(2c), Yb(2d)]. With the ionic radius of rare-earth metal increasing, the reaction of L1H and [(Me3Si)2N]3RE(μ-Cl)Li(THF)3 gave dinuclear (L1)2RE(μ-Cl)(μ-η5:η1:η1-L1)RE(L1)[N(SiMe3)2]2 [RE = Sm(1e), Pr(1f)]; however, the reaction of L2H and [(Me3Si)2N]3Sm(μ-Cl)Li(THF)3 afforded (L2)2Sm[N(SiMe3)2]2 (2e). The ionic radius of rare-earth metal and subtle change in the ligands have substantial effects on the structure and bonding mode of complexes. The complexes showed a high catalytic activity for the ring-opening reaction of cyclohexene oxide with amines to afford various β-aminoalcs. under mild solvent-free conditions. In the experiment, the researchers used many compounds, for example, Trans-2-(benzylamino)cyclohexanol (cas: 40571-86-6Application of 40571-86-6).
Trans-2-(benzylamino)cyclohexanol (cas: 40571-86-6) 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. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.Application of 40571-86-6
