Questions tagged [amines]

For questions about amines - organic compounds with a basic nitrogen with a lone pair, also occasionally referred to as derivatives of ammonia. Not to be confused with amides, for which the tag [carbonyl-compounds] is to be used.

Amines are organic compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are derivatives of ammonia, wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group. - Wikipedia

Note that amides are different from amines and they exhibit different chemical and physical properties.

What factors promote amine inversion? Like bulky groups around the nitrogen atom or less sterically crowding groups? Are there any other factors that affect amine inversion? Does the electronegativity of the atoms bonded to nitrogen affect amine…

Acid in Imine Formation

Why is a strong acid like $\ce{H2SO4}$ used for imine formation here instead of a weaker acid like TsOH? I thought that if the pH was too low, the amine molecule would get protonated to an ammonium, which are not nucleophilic?

Decomposition of aliphatic diazo compounds

The oxidation of hydrazones produce a diazo compound: orgsyn.org - DIAZOPROPANE. An intermediate in the Bamford-Stevens reaction is a diazo moiety. When 2-diazopropane decomposes, does it produce 1-propene? Generally speaking, do diazo compounds…
