Abstract: 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.

Abstract: A process for addition curing organosilicone compositions using as catalysts rodium- or iridium-nitrogen complex compounds having the formulae:(a) monometallic complexes, (L)MX(Y).sub.2, and(b) bimetallic complexes, (L) [RhX(CO).sub.2 ].sub.2, whereinM is a rhodium or iridium metal atom,L is a single or fused heterocyclic ligand comprising at least one five- or six-membered ring, said ligand having 2 to 4 ring nitrogen atoms in the same ring,Y is an uncharged ligand that fills one or two coordination positions of the metal atom, andX is Cl, Br, I, or CN.Preparation of the novel catalysts is disclosed. The cured compositions are useful as molded articles, such as gaskets, O-rings, and tubing.
