The germane [Ge(H)(2-C6H4PPh2)3] (2) was synthesized by reaction of Li[Ge(2-C6H4PPh2)3] (1) with water. The presence of nBuBr led to the formation of [Ge(nBu)(2-C

Rhodium complexes {(Ph2P)C6H4} 3ERh(CO) (1: E = Si; 2: E = Ge; 3: E = Sn) bearing EP3-type tetradentate ligands were synthesized by the reaction of the corresponding ligand precursors HE(o-C6H4PPh2)3 with tris(triphenylphosphine) carbonyl rhodium hydride RhH(CO)(PPh 3)3. In these complexes, the group 14 elements E exhibited a high σ-electron donor ability and elongated the Rh-CO bond trans to E in the order (H ?) Sn ≈ Ge 3 substitution reactions. The substitution of 1 is remarkably slower than those of 2 and 3, and the relative ratios of the pseudo-first-order rate constants kobs for 1, 2, and 3 are 1:7.7:8.5. The kinetic study indicated that heavy group 14 elements E could induce the dissociation of a phosphine ligand cis to E, which eventually leads to CO/L substitution.
