  Described is a carbonylation process using novel homogeneous trihydrocarbyl silyl-substituted alkyl diaryl phosphine transition metal complexes of the general formula: [(Ar.sub.2 PQ).sub.y SiR.sub.4 --y].sub.g (MX.sub.n).sub.s wherein Ar is a C.sub.6 to C.sub.10 aromatic hydrocarbyl radical, Q is a C.sub.1 to C.sub.30 saturated straight chain divalent radical, R is a C.sub.1 to C.sub.10 hydrocarbyl, wherein Ar, Q and R, can be substituted or unsubstituted, y is 1 to 4, g times y is 1 to 6, M is a transition metal selected from the group consisting of Group VIII transition metals, X is an anion or organic ligand excluding halogen satisfying the valence and coordination sites of the metal, n is 2 to 6 and s is 1 to 3, are disclosed. These materials exhibit high thermal stability and are superior catalysts for the selective hydroformylation of olefins, particularly in the presence of excess quantities of ligand of the formula: (Ar.sub.2 PQ)ySiR.sub.4-y wherein Ar, Q, R, and y are as previously defined. Specifically, tris-(trimethyl silyl-ethyl diphenyl phosphine) rhodium carbonyl hydride, [(CH.sub.3).sub.3 Si--CH.sub.2 CH.sub.2 --PPh.sub.2 ].sub.3 Rh(CO)H and tris [bis-(diphenylphosphinoethyl)dimethyl silane] rhodium carbonyl hydride, [(CH.sub.3).sub.2 Si--CH.sub.2 CH.sub.2 --PPh.sub.2 ].sub.3 Rh(CO)H, are selective olefin hydroformylation catalysts, particularly in the presence of excess trihydrocarbyl silyl-substituted alkyl diaryl phosphine ligand.
