The Chemistry of Vicinal Diamines

“…[73] Nevertheless, there are some methods that allow such olefin ªdiaminationº, which mainly use organometallic reagents.…”

Platinum‐Catalyzed Intermolecular Hydroamination of Alkenes: Halide‐Anion‐Promoted Catalysis

“…per mol of the Pt species) for 10 h at 150°C [Equation (10)]. The major product formed was the Markovnikov-type addition product N-(2-hexyl)aniline (12). The other regioisomer (anti-Markovnikov-type), N-(n-hexyl)aniline (13), formed in much lower amounts (12/13 ≈ 95:5).…”

“…Several reviews have been published since 1983. [12][13][14][15][16][17][18][19][20][21][22][23] The main conclusion that can be given (in 2006) is that significant progress has been made for the hydroamination of vinylarenes [24] and dienes, [25] which includes the inter-and intramolecular versions of this reaction. The hydroamination of vinylarenes must be highlighted since catalysts that allow fully regioselective additions (Markovnikov or anti-Markovnikov) and enantioselective Markovnikov additions have been designed.…”

Copper(II) ion-exchanged montmorillonite as catalyst for the direct addition of NH bond to CC triple bond

“…Among the addition reactions, the addition of N H bonds across the CC multiple bonds known as hydroamination is of considerable interest in organic synthesis [1]. It is thermodynamically feasible reaction where amines can be obtained directly without any by-product.…”
