Abstract:
Mechanochemistry turned out to be a powerful synthetic tool enabling the first efficient synthesis of nickel(II) complexes with diphosphines. It has been demonstrated that solventless ball-milling of nickel(II) halides with diphosphines leads to the [NiX2(diphosphine)] type compounds, which can be directly used in catalysis without any purification. Moreover, it was confirmed that despite the presence of impurities in the resulting complexes, their catalytic activity remains identical to those obtained via traditional solvent-based methods.

02:17Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
02:24Reduction 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.
