Abstract
Chlorotris(triphenylphosphine)rhodium (1) is a potentially useful reagent for the decarbonylation of organic carbonyls such as aldehydes, acyl halides, thioesters, and acyl cyanides, as well as metal carbonyls. Both the organic and organometallic decarbonylation reactions are stoichiometric in rhodium with complex 1 being converted to trans-Rh(Cl)(CO)(PPh[sub 3])[sub 2] (2). The expense of rhodium metal coupled with the stoichiometric nature of these transformations has limited the applications of this potentially useful chemistry for 25 years. Prior attempts to recycle the rhodium metal by reconversion of 2 to 1 have been frustrated by the stability of the rhodium carbonyl complex. The authors now report the first high-yield procedure for conversion of 2 to 1. 17 refs.
