摘要：

The sulfide-linked bis(phenol) tbmpH(2) (tbmp = 2,2'-thiobis(6-tert-butyl-4-methylphenolato)) gives a series of titanium complexes of the formula [Ti(tbmp)X(2)](2) or [Ti(tbmp)(L)X(2)] (L = true-electron ligand, X = one-electron ligand). The molecular structures of [Ti(tbmp)(OiPr)(2)](2) and of [Ti(tbmp){C6H4(CH(2)NMe(2))-2}Cl] were determined by single-crystal X-ray structural analyses. An unusually long titanium-sulfur bond of similar to 270 pm is observed in. both complexes which contain a six-coordinate titanium center. Variable-temperature NMR spectroscopy shows a fluxional coordination of the chelating aryl group in [Ti(tbmp){C6H4(CH(2)NMe(2))-2}Cl].
