Definition of Periplanar. Meaning of Periplanar. Synonyms of Periplanar

- In organic chemistry, anti-periplanar, or antiperiplanar, describes the A−B−C−D bond angle in a molecule. In this conformer, the dihedral angle of the...
- Stereochemistry, a subdiscipline of chemistry, studies the spatial arrangement of atoms that form the structure of molecules and their mani****tion. The...
- ketoximes and N-chloro/N-fluoro imines, with the migrating group being anti-periplanar to the leaving group on the nitrogen. Certain conditions have been known...
- stereochemistry of the starting material. E2 eliminations require anti-periplanar geometry, in which the proton and leaving group lie on opposite sides...
- depending on the enantiomer), anti butane is anti-periplanar, and eclipsed butane is syn-periplanar. Klyne, W & Prelog V. Description of steric relationships...
- clinal (c) a torsion angle between 0° and ±30° or ±150° and 180° is called periplanar (p) a torsion angle between 0° and ±30° is called synperiplanar (sp),...
- clinal (c) and those between 0° and ±30° or ±150° and 180° are called periplanar (p). The two types of terms can be combined so as to define four ranges...
- pyranosides is unreactive. Hyperconjugation is involved when OH-4 is anti-periplanar to the ring oxygen, which can also reduce its reactivity. (Scheme 3) Furthermore...
- stereochemistry arises due to hyperconjugative stabilization arising from the anti-periplanar interaction between the C-X antibonding σ* orbital and the forming bond...
- 1,3-dioxane is formed between O-4 and O-6, the oxygens adapt an anti-periplanar geometry with O-5. This orientation allows for hyperconjugation of O-5...
