Abstract:
The transition-metal-catalyzed ring-opening functionalization of aziridines presents a promising approach for synthesizing structurally complex amines. However, the rearranged functionalization of aziridines poses significant challenges. Herein, we report the first rearranged alkenylation of aziridines with aryl alkenes via Ni-Brønsted acid co-catalysis, leading to the rapid synthesis of a diverse array of allylamines with yields reaching up to 91%. Mechanistic studies suggest that the reaction occurs through the rearrangement of aziridine to generate an imine intermediate. This intermediate is subsequently captured by an alkene under nickel catalysis, ultimately leading to the formation of allylamines.

Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
Preparation of Alkynes: Alkylation Reaction
Alkylation of terminal alkynes with primary alkyl halides in the presence of a strong base like sodium amide is one of the common methods for the synthesis of longer carbon-chain alkynes. For example, treatment of 1-propyne with sodium amide followed by reaction with ethyl bromide yields 2-pentyne.

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
