Titanocene(III) chloride [Cp2TiCl, bis(cyclopentadienyl)titanium(III) chloride] is an oxygen-sensitive compound that is prepared by reaction of Cp2TiCl2 with metals such as zinc, aluminum, or manganese. Cp2TiCl exists as a dimer in the solid state, but coordinating solvents (e.g., tetrahydrofuran) dissociate the dimer into a reactive monomer (eq 1).1,2 (Although the monomer is coordinated with a solvent molecule, it usually is represented simply as Cp2TiCl; more generally, Cp2TiCl can be looked upon as representing all the Ti(III) species present in a solution of titanocene(III) chloride.1–3)
