Abstract:
A practical nickel-catalyzed decarboxylative cross-coupling of N-hydroxyphthalimide esters with 1,4-diiodobenzene analogues has been developed. Under mild reaction conditions, a series of structurally interesting 1,4-dialkylbenzene analogues have been accessed with good functional group tolerance, which are versatile precursors for organic synthesis and a kind of important unit for bioactive molecules, polymers, and other materials. The synthetic application of this methodology was demonstrated by the synthesis of 3-6-dialkylcarbazole derivatives.

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.
