Divergent gold catalysis enables the synthesis of distinct products from single starting materials by adjusting the gold catalyst. This review consolidates these findings to advance the field.
Area of Science:
- Catalysis
- Organic Synthesis
- Organometallic Chemistry
Background:
- Divergent catalysis allows diverse products from common substrates by modifying catalysts.
- Gold complexes offer unique reactivity due to electronic and geometric properties.
- Gold catalysts provide divergent pathways for alkynes, alkenes, and allenes, outperforming other π-acid catalysts.
Purpose of the Study:
- To consolidate scattered reports on divergent gold catalysis (DGC).
- To provide a unified approach for advancing DGC.
- To classify DGC based on factors influencing product divergence.
Main Methods:
- Review of literature on gold-catalyzed divergent synthesis.
- Classification of DGC based on governing factors.
- Inclusion of mechanistic insights to explain reactivity and selectivity.
Main Results:
- Gold catalysts enable divergent synthesis, offering reactivity switches via ligand, counteranion, or oxidation state tuning.
- A classification system for DGC is proposed.
- Mechanistic explanations for observed divergence are provided.
Conclusions:
- Divergent Gold Catalysis (DGC) is a powerful strategy for synthesizing structurally distinct molecules.
- Consolidating and classifying DGC facilitates further research and development.
- Understanding mechanistic underpinnings is crucial for controlling divergent outcomes.

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...

Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.
