Cyclohexane stereochemistry

WebSTEREOCHEMISTRY OF REACTIONS When two groups on a substituted cyclohexane conflict in their preference for the equator-ial position, the preferred conformation can usually be predicted from the relative conforma-tional preferences of the two groups. Consider, for example, the chair interconversion of cis-1-tert-butyl-4-methylcyclohexane. WebAug 19, 2024 · cyclohexane: [noun] a pungent saturated cyclic hydrocarbon C6H12 found in petroleum or made synthetically and used chiefly as a solvent and in organic synthesis.

WebCyclohexane is a prototype for low-energy degenerate ring flipping. Two 1 H NMR signals should be observed in principle, corresponding to axial and equatorial protons. However, due to the cyclohexane chair flip, only one signal is seen for a solution of cyclohexane at room temperature, as the axial and equatorial proton rapidly interconvert ...
