text: 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)(PPh) does decarbonylate, however these high temperatures are often prohibitive. The ideal Tsuji–Wilkinson decarbonylation would be by catalytic near ambient temperatures. 
  The reaction has been carried out in flow conditions at low temperatures in which a biphasic liquid-gas flow decarbonylation was developed employing N as a gas carrier. However, the temperature required for this reaction is 200 °C.
  Significant improvements of the Tsuji–Wilkinson decarbonylation have been made by using cationic rhodium complexes with chelating bisphosphines.
