ABSTRACT:
The hydroformylation of olefins with rhodium complex catalysts is described. The catalysts employed comprises a rhodium complex with at least one phosphine having a specified structure, e.g., tris(benzyl)phosphine. Preferred phosphines have a pKa in the range of about 3.5 up to 5.3 and a cone angle in the range of about 160.degree. up to 195.degree.. Hydroformylation reactions at relatively low temperatures and pressure and yet with high rates of reaction and high selectivity to aldehyde product are obtained by the practice of the present invention.
