Catalytic Strategies for Amide‐Based Michael Additions: Advances and Perspectives

Journal of Chemistry, Volume 2026, Issue 1, 2026.
The Michael addition is a cornerstone transformation in organic synthesis, enabling efficient C–C and C–heteroatom bond formation. Traditionally, α,β‐unsaturated carbonyl compounds such as enones and esters have dominated as Michael acceptors, whereas α,β‐unsaturated amides remain underutilized due to their strong resonance stabilization and low ...

Transfer Hydrogenation: Advances in Manganese and Nickel Metal Catalysis

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Transfer hydrogenation (TH) of ketones, catalyzed by transition–metal complexes, produces alcohols, which are important building blocks in the pharmaceutical and fine chemical industries. For a long time, catalysts based on noble metals such as ruthenium, rhodium, and iridium have dominated the TH of ketones.
