Übersetzung für 'Z E isomerism' von Englisch nach Deutsch

Z/E isomerism

(Z)-(E)-Isomerie {f}chem.

• Systematically, it is called a but-2-en-1-yl group and exhibits geometric isomerism, being either "cis" ("Z") or "trans" ("E").
• (scheme 23) The unprotected N-H ketimines alleviate problems caused by E/Z isomerism in the asymmetric catalytic reactions, although they generally have lower stability.
• For most 1,2-disubstituted compounds that exhibit "cis"–"trans" isomerism, the "trans" ("E") isomer is more stable than the "cis" ("Z") isomer.
• In E- and Z- isomerism, each functional group is assigned a priority based on the Cahn–Ingold–Prelog priority rules.
• Anomerism is an identity for single bonded ring structures where "cis" or "Z" and "trans" or "E" (geometric isomerism) needs to name the substitutions on a carbon atom that also displays the identity of chirality; so anomers have carbon atoms that have geometric isomerism and optical isomerism (enantiomerism) on one or more of the carbons of the ring.
