This invention relates to rhodium compounds having the general formula: HRh(CO)(XR.sub.3).sub.n (YR'.sub.3).sub.3-n wherein X is phosphorus, arsenic or antimony; Y is arsenic or antimony when X is phosphorus, Y is phosphorus or antimony when X is arsenic, or Y is phosphorus, arsenic or antimony when X is antimony; R and R' are aryl groups; and n is an integer of 1 or 2. Further, it relates to a process for the preparation of aldehydes by the hydroformylation of olefins in the presence of a rhodium catalyst, and more particularly for the production of aldehydes by the reaction of olefins such as propylene with carbon monoxide and hydrogen in the presence of HRh(CO)(PPh.sub.3).sub.2 (AsPh.sub.3)/excess PPh.sub.3 and AsPh.sub.3 or HRh(CO)(PPh.sub.3)(AsPh.sub.3).sub.2 /excess PPh.sub.3 and AsPh.sub.3.
A process for the hydroformylation of olefins by the reaction of an olefin with carbon monoxide and hydrogen to produce an aldehyde having one more carbon atom than the olefin wherein there is used as catalyst at temperatures in the range of ambient to about 150.degree. C., a total pressure in the range of atmospheric to about 100 atmospheres and a H.sub.2 /CO mol ratio of 10/1 to 1/10, a preformed rhodium complex having the general formula
