Reaction of ( i Pr 2 NP) 2 COFE 2 (CO) 6 with benzyllithium (from PhCH 2 SnPh 3 + n -Buli) gives the corresponding tertiary alcohol ( i Pr 2 NP) 2 C(CH 2 Ph)(OH)Fe 2 (CO) 6 , which has been characterized structurally by X-ray diffraction (monoclinic; space group, P ...

Only the tertiary alcohol group reaches out of this binding cleft. b, Close-up of CRID binding to subdomains NBD, HD1 and WHD (left) and HD1, WHD, HD2 and trLRR (right). To visualize the binding sites, the other subdomains in each case were omitted. c, Density map around CRID3 ...
Far u.v. circular dichroism spectroscopy revealed a greater proportion of α-helix structure in the presence of alcohol; the effectiveness of the alcohol in causing this structural change increased in the order methanol to 2,2,2-trifluoroethanol. No alterations in secondary or tertiary structure ...
The tertiary alcohol alpha-(9H-fluoren-2-yl)-alpha-methyl-1H-imidazole-1-ethanol was as potent as denzimol in mice (po ED50's = 10 and 12 mg/kg, respectively). This series of imidazole anticonvulsants was highly selective; while many compounds displayed potent antielectroshock activity, ...
David Rawn, in Principles of Organic Chemistry, 2015 Quaternary Structure The quaternary structure of a protein is the association of several protein chains or subunits into a closely packed arrangement. Each of the subunits has its own primary, secondary, and tertiary structure. The subunits are ...
They can be produced from an alcohol or an alkene. Alkyl Halide Structure As mentioned, the alkyl halide structure differs from alkanes due to the replacement of a hydrogen atom with a halogen atom. The structure can be classified as primary, secondary, or tertiary, based on the number of ...
Tertiary structure of CgrAlcOx and metal site geometry. The 3D structure of CgrAlcOx was solved using the homologous two domains of FgrGalOx as the model. Surprisingly, given the dif- ficulty of demetallating with EDTA, crystals grown in 0.1 M imidazole were copper-free. A copper-...
Molecular structuresof high complexity can be synthetized under visible light by using C3N4as heterogeneous photocatalyst. Formation of imines as benzoxazoles, benzimidazoles, or benzothiazoles from benzylamine has been presented above[17]. In addition, reaction (Mannich reaction) of tertiary amines (tetr...
