Synthesis of Cp*₂Ti(OTf) and Its Reaction with Water

Abstract

Abstract Cp* 2 Ti(OTf) ( 2 ) was prepared by oxidation of the known(alkyne)titanocene complex Cp* 2 Ti(η 2 ‐Me 3 SiC 2 SiMe 3 ) with Fe(OTf) 3 . This reaction is highly selective; formation of Cp* 2 Ti(OTf) 2 by using an excess of the oxidizing agent was not observed. Complex 2 was treated with water to give Cp* 2 Ti(OH)(OTf) ( 5 ) and hydrogen gas. This reaction was monitored by GC and volumetric analysis. Complexes 2 and 5 were characterized by X‐ray crystallography and investigated by DFT analysis.
