Definition of Antiperiplanar. Meaning of Antiperiplanar. Synonyms of Antiperiplanar

- 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...
- simultaneous removal of a proton and a leaving group from vicinal or antiperiplanar positions under the influence of a base. The mechanism requires that...
- leaving groups (often a hydrogen and a halogen) need to be antiperiplanar. An antiperiplanar transition state has staggered conformation with lower energy...
- the necessity of the oxygen-oxygen bond in the peroxide group to be antiperiplanar to the group that migrates. This orientation facilitates optimum overlap...
- hyperconjugation is that the bonds donating and accepting electron density are antiperiplanar to each other, to allow for maximum orbital overlap. The Cieplak effect...
- (ac); ±150° to 180° antiperiplanar (ap). The synperiplanar conformation is also known as the syn- or cis-conformation; antiperiplanar as anti or trans;...
- = 180 ∘ {\displaystyle \omega =180^{\circ }} for the trans isomer (antiperiplanar conformation). Amide groups can isomerize about the C'–N bond between...
- of Br− from the back side. This yields the vicinal dibromide with an antiperiplanar configuration. When other nucleophiles such as water or alcohol are...
- conformation energy diagram of butane as a function of dihedral angle. A: antiperiplanar, anti or trans. B: synclinal or gauche. C: anticlinal or eclipsed. D: synperiplanar...
- called anticlinal (ac) a torsion angle between ±150° to 180° is called antiperiplanar or anti or trans (ap). Torsional strain results from resistance to twisting...
