摘要：

We have been interested in the fundamental nature of the reactivity of early metal-sulfur bonds for some time. A variety of group four metal sulfide derivatives are known, including mono and dimetallic compounds such as (η5-C5H5)2TiS5, 1,5-((η5-C5H5)2Ti) 2S6, and 1,4-((η5-C5H5)2Ti) 2S45, as well as the higher nuclearity aggregates [(η5-C5H5)TiS]4, (η5C5H5)5 Ti5S6, Zr3S3(t-BuS)2(BH4)4 (THF)2, Zr6S6(t-BuS)4 (BH4)8-(THF)2, Zr3S(S-t-Bu)10, ((η5-C5H5)Ti)4 (μ3-S)3 (μ2-S)(μ2-SEt)2, ((η5-C5H5)Ti)6 (μ3-S)4(μ3-O)4, and [(η5-C5H5)Ti (OC6H3-2,6-i-Pr2) (μ3-S)]3Ti(η5- C5H5). In contrast, group four complexes containing terminal-sulfido ligands are much less common, being limited to [Ti(S)Cl4], (η5-C5Me5)2M(S)py (M = Ti, Zr, Hf), [(η5-C5H5)Ti(μ-S)(S)]2, and (PhC(NSiMe3)2))2Ti(S)py. In our own work, we have been exploring the effects of bulky aryloxide ligands in Ti-sulfide chemistry. We have previously reported dimetallic sulfide bridged complexes of the form [(η5-C5H5)Ti (OC6H3-2,6-i-Pr2)(μ-S)]2 and [(η5-C5H5)Ti (OC6H3-2,6-i-Pr2)]2 (μ-S)(μ-S2). In the present work, we probe several strategies in quest of titanium-terminal-sulfide complexes.
