Abstract:
We report herein the first example of Cu(II)-catalyzed site selective azidation of aromatic amines via C-H functionalization in aqueous media. In our strategy, a mild reagent was utilized. H2O2 served as the oxidant, and sodium azide was used as the azidation reagent. This method could also be applied to late-stage functionalization of drugs that possess an aromatic amine moiety. In addition, we found that bromination or iodination on the ortho-position of aromatic amines could occur efficiently using this catalytic system.

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...

Alkynes to Aldehydes and Ketones: Acid-Catalyzed Hydration
Analogous to alkenes, alkynes also undergo acid-catalyzed hydration. While the addition of water to an alkene gives an alcohol, hydration of alkynes produces different products such as aldehydes and ketones.
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.
