摘要：

Mixed-amido Ti(IV) compounds of the type Ti(NR'(2))(2)[N(SO2R)CHPhCHPhN(SO2R)] (R' = Me, Et; R = p-C6H3CH3, p-C6H4C(CH3)(3), CF3) were synthesized by the aminolysis of Ti(NR'(2))(4) with bis(sulfonamide) ligands 1a-c. The structure of compound 3b, determined by X-ray crystallography, indicates that une oxygen from a single SO2 group binds to the metal center in the solid state, breaking the C-2 symmetry. These Ti-bis(sulfonamide) complexes, when treated with 2,6-dimethylphenol, generate putative Ti(OAr)(2)(bis(sulfonamide)) intermediates which display unorthodox disproportionation behavior.
