Mono- and Bis-Titanium Complexes Bridged by 2‑Butene Tetraanion: Synthesis and Structural Characterization

An unprecedented class of organo-dimetallic compounds, mono-titanium (Ti/Li) and bis-titanium (Ti/Ti) complexes bridged by 2-butene tetraanionic ligands, were obtained from the reaction of dilithio reagents 1 with TiCl2(TMEDA) or TiCl4, respectively. The Ti/Li complex could be transformed to the Ti/...

Description
Summary:An unprecedented class of organo-dimetallic compounds, mono-titanium (Ti/Li) and bis-titanium (Ti/Ti) complexes bridged by 2-butene tetraanionic ligands, were obtained from the reaction of dilithio reagents 1 with TiCl2(TMEDA) or TiCl4, respectively. The Ti/Li complex could be transformed to the Ti/Ti complex when treated with TiCl3(THF)3. Mechanistic study demonstrated that the dilithio reagents 1 acted as both reductant and oxidant in the reaction process.
