Tsuji-wilkinson decarbonylation

WebDec 26, 2024 · The Tsuji–Wilkinson decarbonylation proceeds under mild conditions and is highly stereospecific. In addition to aliphatic, aromatic, and α,β-unsaturated aldehydes, … WebHerein, an efficient Rh-catalyzed deuterated Tsuji–Wilkinson decarbonylation of naturally available aldehydes with D₂O is developed. In this reaction, D₂O not only acts as a deuterated reagent and solvent but also promotes Rh-catalyzed decarbonylation.
