    摘要: Coordination compounds of rhodium are solid salts having donor ligands of [(aryl).sub.3 P].sub.3 Rh.sup.+ and a non-coordinated counterion derived from a fluorochemical acid, the salts having the formula:[(aryl).sub.3 P].sub.3 Rh.sup.+ (counterion).sup.-.The salts are prepared by reacting [(aryl).sub.3 P].sub.4 RhH, which is an uncharged rhodium hydride, with a fluorochemical acid selected form acids having the formulae:HC(R)(SO.sub.2 R.sub.f).sub.2, R.sub.f 'SO.sub.3 H, and HN(SO.sub.2 R.sub.f).sub.2wherein R.sub.f and R.sub.f ' are perfluoroalkyl groups and R is lower alkyl substituted or unsubstituted phenyl, hydrogen, Cl, SO.sub.2 R.sub.f or R.sub.f. Carbonylation of the [(aryl).sub.3 P].sub.3 Rh.sup.+ (counterion).sup.- compounds of this invention, e.g., by contacting the salts of the invention with carbon monoxide gas, produces salts having the formula:[(aryl).sub.3 P].sub.3 Rh(CO).sub.n.sup.+ (counterion).sup.-,wherein n is 1 or 2, and (counterion).sup.- is as defined above. These carbonylated derivatives as well as the above-described precursor salts are useful as catalysts in organic transformation reactions, such as isomerization, cyclization and hydroformylation reactions.
