Published: March 5, 2024

Catalytic transfer hydrogenation (CTH) methodology has drawn profound attention of researchers as an economical and environmentally benign alternate to conventional method. Unlike method, CTH exhibits better reaction efficiency atom economy, it makes use simple, easily accessible, low-cost hydrogen sources. Current research on reactions is oriented toward the development non-noble-metal-based catalysts due their high abundance potential large-scale applicability. In this Review, different organic transformation reactions, such nitroarenes, nitriles, alkenes, alkynes, carbonyl compounds, hydrogenolysis, reductive amination, formylation using sources have been summarized comprehensively. addition, synthesis strategies heterogeneous structure–activity relationship involving metal–support interaction, single-atom catalysis, synergistic effect are highlighted. Furthermore, optimization parameters─such temperature, time, solvents, additives─for enhancing catalytic activity selectivity product discussed in detail. This Review provides detailed insights into recent progress made with a specific focus catalyst development, sources, mechanistic exploration.

Photocatalytic Hydrogenation of Alkenes Using Water as Both the Reductant and the Proton Source

Advanced Science, Journal Year: 2024, Volume and Issue: 11(44)

Published: Oct. 9, 2024

Abstract Utilization of clean and low‐cost water as the reductant to enable hydrogenation alkenes is highly attractive in green chemistry. However, this research subject considerably challenging due sluggish kinetics oxidation half‐reaction. It also very difficult avoid undesired because that far easier occur than desired from thermodynamic standpoint. Herein, challenge overcome by applying a cooperative catalysis where HCl used cocatalyst accelerate Pt/g‐C 3 N 4 ‐catalyzed suppress alkene. This provides an example for using proton source photocatalytic alkenes. The present method exhibits broad substrate applicability, allows various arylethenes aliphatic undergo smoothly.
