Amine alkylation (amino-dehalogenation) is a type of organic reaction between an alkyl halide and ammonia or an amine. [1] The reaction is called nucleophilic aliphatic substitution (of the halide), and the reaction product is a higher substituted amine. The method is widely used in the laboratory, but less so industrially, where alcohols are ...
In general, the reaction of a haloalkane with potassium hydroxide can compete with an S N 2 nucleophilic substitution reaction by OH − a strong, unhindered nucleophile. Alcohols are however generally minor products. Dehydrohalogenations often employ strong bases such as potassium tert-butoxide (K + [CH 3] 3 CO −).
Upon workup by acidic hydrolysis the primary amine is liberated as the amine salt. [11] Alternatively the workup may be via the Ing–Manske procedure, involving reaction with hydrazine. This method produces a precipitate of phthalhydrazide (C 6 H 4 (CO) 2 N 2 H 2) along with the primary amine: C 6 H 4 (CO) 2 NR + N 2 H 4 → C 6 H 4 (CO) 2 N 2 ...
In chemistry, ammonolysis (/am·mo·nol·y·sis/) is the process of splitting ammonia into + +. [1] Ammonolysis reactions can be conducted with organic compounds to produce amines (molecules containing a nitrogen atom with a lone pair, :N), [2] or with inorganic compounds to produce nitrides.
The Stieglitz rearrangement is especially reactive in the case of bridged bicyclic N-sulfonated amines as starting materials, where mild conditions are sufficient for an efficient reaction to take place. [23] For example, the rearrangement of the bicyclic N-tosylated amine proceeds readily in aqueous dioxane at room temperature. [24]

Tetrafluoroethane (a haloalkane) is a colorless liquid that boils well below room temperature (as seen here) and can be extracted from common canned air canisters by simply inverting them during use. The haloalkanes (also known as halogenoalkanes or alkyl halides) are alkanes containing one or more halogen substituents. [1]
