Synthesis and structures of ansa-titanocene complexes with diatomic bridging units for overall water splitting

The synthesis of a series of ansa-titanocene dichlorides [Cp' 2TiCl2] (Cp′=bridged η5- tetramethylcyclopentadienyl) and the corresponding titanocene bis(trimethylsilyl)acetylene complexes [Cp′2Ti(η 2-Me3SiC2SiMe3)] is described. The ethanediyl-bridged complexes [C2H4(C5Me 4)2TiCl2] (2-Cl2) and [C 2H4(C5Me4)2Ti(η 2-Me3SiC2SiMe3)] (2-btmsa; btmsa=η2-Me3SiC2SiMe3) can be obtained from the hitherto unknown calcocenophane complex [C2H 4(C5Me4)2Ca(THF)2] (1). Furthermore, a heterodiatomic bridging unit containing both, a dimethylsilyl and a methylene group was introduced to yield the ansa-titanocene dichloride [Me2SiCH2(C5Me4) 2TiCl2] (3-Cl2) and the bis(trimethylsilyl) acetylene complex [Me2SiCH2(C5Me 4)2Ti(η2-Me3SiC 2SiMe3)] (3-btmsa). Besides, tetramethyldisilyl- and dimethylsilyl-bridged metallocene complexes (structural motif 4 and 5, respectively) were prepared. All ansa-titanocene alkyne complexes were reacted with stoichiometric amounts of water; the hydrolysis products were isolated as model complexes for the investigation of the elemental steps of overall water splitting. Compounds 1, 2-btmsa, 2-(OH)2, 3-Cl2, 3-btmsa, 4-(OH)2, 3-alkenyl and 5-alkenyl were characterised by X-ray diffraction analysis. Copyright
