A nickel(0)-catalyzed hydroalkenylation of imines with styrene and its derivatives is described. A wide range of aromatic and aliphatic imines directly coupled with styrene and its derivatives, thus providing various synthetically useful allylic amines with up to 95 % yield. The reaction offers a new atom- and step-economical approach to allylic amines by using alkenes instead of alkenyl-metallic reagents. Experiments and DFT calculations showed that TsNH2 promotes the proton transfer from the coordinated olefin to the imine, accompanied by a new C?C bond formation.

A transition-metal-free oxidative coupling of allylic C-H and heterocyclic/aromatic N-H bonds was performed under mild conditions. Promoted by 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ), up to 99% yield could be achieved. Georg Thieme Verlag Stuttgart, New York.
A new and convenient method for reduction of oximes to amines with NaBH3CN in the presence of MoCl5/NaHSO4? H2O system
Kouhkan, Mehri,Zeynizadeh, Behzad
experimental part, p. 3323 - 3326 (2012/02/04)
Various aldoximes and ketoximes were efficiently reduced to their corresponding amines with NaBH3CN in the presence of MoCl 5/NaHSO4?H2O system. Reduction reactions were carried out in refluxing EtOH or DMF within 0.3-3.8 h to afford the amines in high to excellent yields.
A rapid and practical protocol for solvent-free reduction of oximes to amines with NaBH4/ZrCl4/Al2O3 system
Zeynizadeh, Behzad,Kouhkan, Mehri
experimental part, p. 3448 - 3452 (2012/02/01)
Solvent-free reduction of various aldoximes and ketoximes to the corresponding amines was performed easily and efficiently with NaBH4 in the presence of ZrCl4 supported on Al2O3. The reactions were carried out rapidly (within 2 min) at room temperature to afford the amines in high to excellent yields.
A dual-catalysis/anion-binding approach to the kinetic resolution of allylic amines
