The Tsuji–Wilkinson decarbonylation reaction is a method for the decarbonylation of aldehydes and some acyl chlorides. The reaction name recognizes Jirō Tsuji [de], whose team first reported the use of Wilkinson's catalyst (RhCl(PPh3)3) for these reactions: RC(O)X + RhCl(PPh3)3 → RX + RhCl(CO)(PPh3)2 + … See more Strictly speaking, this reaction results in the formation of a rhodium carbonyl complex rather than free carbon monoxide. The catalytic cycle is assumed to involve oxidative addition of … See more Unfortunately, the Tsuji–Wilkinson decarbonylation is stoichiometric. The product bis(triphenylphosphine)rhodium carbonyl chloride is not readily converted back to a CO-free reagent. Above 200 °C, carbon monoxide RhCl(CO)(PPh3)2 does decarbonylate, … See more The Tsuji–Wilkinson decarbonylation proceeds under mild conditions and is highly stereospecific. In addition to aliphatic, aromatic, and α,β-unsaturated aldehydes, acyl See more • Tsuji, Jiro; Ohno, Kiyotaka (January 1965). "Organic syntheses by means of noble metal compounds XXI.
