We investigated the potential application of low-valent silicon compounds as transition metal ligands by computing the most important ligand properties and compared them to the generally used carbene and phosphine ligands.

Heteronuclear Complex

The reaction of Cp(CO)2Fe-SiHCl2 with Co2(CO)8 yields the heteronuclear complex Cp(CO)2Fe-SiCl2-Co(CO)4 (1) and HCo(CO)4.1 is degradated by AgBF4 to Cp(CO)2Fe-SiF3. PMe3 transforms 1 to Cp(CO)2Fe-SiCl2-Co(CO)3PMe3 (2). LnM-SiH2Me reacts with Co2(CO)8 to give LnM-SiMe-Co2(CO)7 [LnM = Cp(CO)2Fe (3a), Cp(CO)2PMe3W (3b)]. Starting with Cp(CO)2Fe-SiH3, μ3-Cp(CO)2Fe-SiCo3(CO)9 (4), the second example of a μ3-metallosilylidine tricobalt cluster is obtained in high yield, which is cleaved by acetic acid to Cp(C0)2Fe-Si[OC(O)Me]3 (5). The composition and structure of the silicon transition metal complexes 1-5 is proved by NMR, IR and mass spectroscopy. 29Si NMR shifts are determined for the first time for a tri- and tetra-metalated silicon species
