"adjacent" nach Englisch mit Beispielen - Kollokationen-Wörterbuch Englisch
- Tert-butyl radicals have many hydrogens on adjacent carbons to donate and steric effects often prevent tert-butyl radicals from getting close to abstracting hydrogens.
- In the first step, borane (BH) adds to the double bond, transferring one hydrogen from itself to the adjacent carbon.
- From a synthetic point of view, the most challenging structural features of the molecule are the C3 spirocyclic ring juncture and the adjacent prenyl-substituted carbon.
- It resembles a benzene ring, except that two adjacent carbons are replaced by nitrogen and boron, respectively.
- Has the lowest-numbered locants for multiple bonds (The locant of a multiple bond is the number of the adjacent carbon with a lower number).
- The p-orbital at fluorine parallel to the one on the adjacent carbon will face an optimal interaction.
- Next is a concerted migration of one of the adjacent carbons to oxygen with loss of a carboxylic acid.
- In this reaction, sulfur is reduced while adjacent carbon is oxidized.
- What follows is a 1,2-rearrangement when an alkyl substituent on the anionic boron migrates to the adjacent electrophilic carbon of the carbonyl group.
- Subsequently, an alkyl group from the adjacent carbon migrates to the carbocation center.
