A series of titanocene(III) alkoxides L 2Ti(III)OR where L = Cp, R = Et(1b), tBu(1a), 2,6-Me 2C 6H 3(1c), 2,6- tBu 2-4-Me-C 6H 2(1d), or L = Cp*, R = Me(2e), tBu(2a), Ph(2f) was synthesized and subjected to reaction with [CpM(CO) 3] 2 [M = Mo, W], [CpRu(CO) 2] 2, and Co 2(CO) 8. The Ti(III) precursors 1a, 1c, 2a, 2e, and 2f reacted with [CpM(CO) 3] 2 [M = Mo, W] to form heterobimetallic complexes L 2Ti(OR)(μ-OC)(CO) 2MCp [M = Mo, W], of which Ti and M are linked by an isocarbonyl bridge. Reactions of these Ti(III) complexes with Co 2(CO) 8 resulted in formation of Ti-Co 1 heterobimetallic complexes, Cp 2*Ti(O tBu)(μ-OC) Co(CO) 3 from 2a, 2e, or 2f, or Ti-Co 3 tetrametallic complexes, Cp 2Ti(O tBu)(μ-OC)Co 3(CO) 9 from 1a, 1b, or 1c. The products were characterized by NMR, IR, and X-ray crystallography. Reaction mechanisms were proposed from these results, in particular, from steric/electronic effects of titanium alkoxides.
