摘要：

Titanium complexes containing the novel tridentate 2,2'-sulfinylbis (6-tert-butyl-4-methylphenoxo) ligand (sibmp) were synthesized and characterized. Treatment of titanium tetra-iso-propoxide with 2,2'-sulfinylbis(6-tert-butyl-4-methylphenol (sibmpH(2)) in 1:1 molar ratio afforded red-orange, sparingly soluble di-iso-propoxo derivative [Ti(sibmp) (O-i-Pr)(2)](2).0.5 Et2O. The single-crystal structure analysis was performed and revealed a dimeric centrosymmetric structure with a planar Ti2O2 core. The titanium center is approximately octahedral with a S=O function intramolecularly coordinated at the titanium center. Treatment of sibmpH(2) with titanium tetra-iso-propoxide in 2:1 molar ratio gave yellow Ti(sibmp)(2) with a C-2-symmetric spirocyclic structure. The dark red dichloro complex [Ti(sibmp)Cl-2] was prepared by reacting titanium tetrachloride with sibmpH(2). (C) 1998 Elsevier Science Ltd. All rights reserved.
