Understanding the impact of ligand properties on their performance in catalysis is seminal for future ligand design and catalyst improvement. In this work, the influence of the steric and electronic properties on the efficiency of a series of mono- and di

Heterogeneous intermolecular hydroamination of alkynes with aromatic amines using inexpensive transition metal-exchanged clay catalysts was investigated. Reaction of terminal alkynes with aromatic amines gave higher yields of imines.
Ti(NMe2)4-catalyzed Markovnikov hydroamination of alkynes in the presence of N-heterocyclic carbenes and LiN(SiMe3)2

Intermolecular hydroamination of alkynes catalyzed by Ti(NMe2)4 was much improved with N-heterocyclic carbenes and LiN(SiMe3)2, by which high Markovnikov selectivity was attained for the coupling of nearly all a
New C-N and C-C bond forming reactions catalyzed by titanium complexes
Odom, Aaron L.
, p. 225 - 233 (2007/10/03)
Titanium(iv) complexes with two basic dimethylamido ligands can be efficient catalysts for alkyne hydroamination by primary amines. Readily prepared pyrrolyl ligands have proven to be especially useful in generating active catalysts for hydroamination and
Rhodium-mediated 100% regioselective oxidative hydroamination of α-olefins
Brunet,Neibecker,Philippot
, p. 3877 - 3880 (2007/10/02)
The system generated from lithium anilide and [(Et3P)2RhCl]2 caralyzes (turnover 21) the regioselective condensation of aniline with styrene to give a mixture of PhNH-CH(CH3)Ph (hydroamination product) and PhN=C(CH3)Ph (oxidative hydroamination product) in c.a. 1/2 ratio. This 100% regioselective oxidative hydroamination has been confirmed in the case of 1-hexene.
Catalytic and Non-catalytic Addition of Aromatic Amines to Terminal Acetylenes in the Presence of Mercury(II) Chloride and Acetate
Barluenga, Jose,Aznar, Fernando,Liz, Ramon,Rodes, Rosa
, p. 2732 - 2737 (2007/10/02)
The addition of aromatic amines to terminal acetylenes in the presence of catalytic amounts of mercury(II) chloride gives imines, enamines, and 1,2,3,4-tetrahydroquinoline derivatives; mercury(II) acetate shows considerably less catalytic activity and may be used for the non-catalytic preparation of imines, enamines, N,N'-disubstituted acetamidines, and N,N-disubstituted acetamides.
