While the first 25 years of hydroformylation, i.e. oxo-process, chemistry were dominated by cobalt based catalysts, there has been rapid development of rhodium complex hydroformylation catalysts during the last 10 years. Although rhodium is about 100 times more expensive than cobalt, the low pressure activity of some rhodium complex catalysts is highly attractive when compared with the high pressure activity of the main cobalt catalyst, i.e., cobalt tetracarbonyl hydride. As a consequence, new plants for the selective hydroformylation of propylene to n-butyraldehyde, a key intermediate in the production of diethylhexyl phthalate plasticizer, have been for the most part based on a triphenylphosphine (Ph/sub 3/P) rhodium complex catalyst system, jointly developed by Union Carbide Corporation and Davy McKee Ltd. The mechanism of this catalyst system, which is presently of paramount importance in rhodium hydroformylation, is the main topic of the present paper.
