Selective Dilithiation of [Ti(eta(5)-C2H5)(eta(8)-C8H8)] and Subsequent Conversion into Neutral and Cationic ansa-Complexes
Selective dimetalation of a sandwich complex featuring the cyclooctatetraene ligand has been accomplished for the first time. The isolation of the dilithiated species 1 subsequently enabled the isolation of a paramagnetic [2] stannatitanoarenophane (2) via salt elimination reaction. Chemical oxidation resulted in the formation of a rare example of a cationic ansa-complex (3).
