Homogeneous organic reductants offer advantages over traditional heterogeneous reductants in nickel-catalyzed cross-electrophile coupling (XEC) reactions. This perspective explores their potential for broader synthetic applications.
Area of Science:
- Organic Chemistry
- Catalysis
- Synthetic Methodology
Background:
- Many organic reactions, including Ni-catalyzed cross-electrophile coupling (XEC), rely on reductants.
- Heterogeneous reductants (e.g., Zn 0, Mn 0) are common but pose challenges for process scale and flow chemistry.
- Homogeneous organic reductants offer potential solutions and tunable reactivity.
Purpose of the Study:
- To review the progress of homogeneous organic electron donors in Ni-catalyzed XEC.
- To discuss the synthetic and mechanistic advantages of these reductants.
- To identify limitations and future challenges for their widespread adoption.
Main Methods:
- Literature review and perspective on homogeneous organic reductants in Ni-catalyzed XEC.
- Analysis of synthetic benefits and mechanistic insights.
- Discussion of limitations and future research directions.
Main Results:
- Homogeneous organic reductants can overcome limitations of heterogeneous reductants in XEC.
- They offer precise control over reductant strength and potential for new reactivity.
- Challenges remain in their broad implementation in synthetic chemistry.
Conclusions:
- Homogeneous organic reductants represent a promising alternative for reductive transformations.
- Further research is needed to address implementation challenges for wider synthetic utility.
- This approach has implications beyond XEC for various reductive processes.

Reduction 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...
Electron Carriers

Reduction 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.
Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...
