摘要：

A novel carboranyl-thiol-appended cyclopentadiene ligand, 1-SH-2-[HCpCH(Ph)]-closo-1,2-C2B10H10 (2), was prepared and then reacted with Ti(NMe2)(4) to form the corresponding titanium complex [1-(sigma-S)-2-(eta(5)-C5H4CH(ph))-1,2-C2B10H10)]Ti(NMe2)(2) (3), which undergoes exclusively a monohalogenation reaction on the metal center, in the presence of Me3SiCl or Me3NHCl, leading to the formation of [1-(sigma-S)-2-(eta(5)- C5H4CH(Ph))-1,2-C2B10H10)]TiCl(NMe2) (4) in 71% yield.
