Web31 Jan 2024 · There is a clever workaround to this – at least for the synthesis of primary amines. It’s called the “Gabriel Synthesis”. 1. The Gabriel Synthesis Uses A “Protected” Amine (Phthalimide) In An S N 2 Reaction That Does Not Undergo Over-Alkylation. In the Gabriel synthesis we start with a molecule called “phthalimide”.

WebThe azide anion. In chemistry, azide is a linear, polyatomic anion with the formula N− 3 and structure −N=N+=N−. It is the conjugate base of hydrazoic acid HN3. Organic azides are organic compounds with the formula RN3, containing the azide functional group. [1] The dominant application of azides is as a propellant in air bags. WebA better method for preparing primary amines is to use the azide synthesis, in which azjde ion, N3, is used for SN2 reaction with a primary or secondary alkyl halide to give an alkyl azide, RN3. Because alkyl azides are not nucleophilic, overalkylation can t occur.
