Complex rhodium compounds containing rhodium in combination with the ligands carbon monoxide and a plurality of triarylphosphines and have the formulae: [(aryl3P)2Rh(CO)(alkylCN)]8-nX+nM12O40,I [(aryl3P)2Rh(CO)(alkylCN)]9-nX+nM12O40,II [(aryl3P)2Rh(CO)]8-nX+nM12O40,III [(aryl3P)2Rh(CO)]9-nX+nM12O40,IV [(aryl3P)2Rh(CO)3]8-nX+nM12O40,V and [(aryl3P)2Rh(CO)3]9-nX+nM12O40,VI wherein alkyl is lower alkyl (C1 to C4), X is a transition element selected from Periodic Table groups IIIA, IVA, VA, or VIII, aryl can be phenyl or phenyl substituted by 1 to 3 lower alkyl (C1 to C4) and lower alkoxy (C1 to C4) groups, M is molybdenum (Mo) or tungsten (W), and n is an integer having a value 2 to 5. These novel complex rhodium compounds catalyze the hydroformylation of olefins to provide carboxylic acids, the oxidation of carbon monoxide to form carbon dioxide, the isomerization of terminal to internal olefins and the reduction of nitric oxide to nitrous oxide by carbon monoxide. |
