Abstract: The invention relates to a process for preparing diketonato-rhodium(I)-carbonyl complexes, especially diketonato-rhodium(I)-triorganophosphine-carbonyl complexes, for example Rh(CO)(PPh3)acac. The process according to the invention is a “one-pot synthesis” and features a process procedure without intermediate isolation stages. After introduction of an Rh(III) halide precursor into a solvent and sparging with carbon monoxide (CO), a diketo compound of the R?—C(?O)—CH2—C(?O)—R? type and a base are added, forming the intermediate compound diketonato-Rh(CO)2. After addition of a triorganophosphine of the PR3 type, the reaction mixture is heated and the diketonatocarbonyltriorganophosphine-rhodium(I) complex is removed. The process enables a rapid operation and a high yield. The complex Rh(CO)(PPh3)acac prepared in accordance with the invention, because of its purity, is particularly suitable as a catalyst or precatalyst for homogeneous catalysis, for example for hydroformylation reactions.
