摘要	Syntheses and structures of five imido-bridged dinuclear titanium complexes and two (bis)ligand-coordinated mononuclear titanium complexes are reported. Addition of 1 or 2 equiv. of Schiff base ligand (((1H-pyrrol-2-yl)methylene)amino)-2,3-dihydro-1H-inden-2-ol (H2L) to Ti(NMe2)(4) resulted in transamination with 4 equiv. of dimethylamides generating a (bis) ligand-coordinated complex Ti(L)(2) (1). Treatment of Ti(NMe2)(4) with 1 equiv. of (BuNH2)-Bu-t followed by addition of 1 equiv. of H2L afforded an imido-bridged complex [Ti(L)((NBu)-Bu-t)](2) (2). 1: 1: 1: 1 reaction of Ti(NMe2)(4)/RNH2/H2L/py(or phen) produced imido-bridgedcomplexes [Ti(L)(NPh)(py)](2) (3), [Ti(L)(4-F-PhN)(py)](2)center dot Tol (4 center dot Tol), [Ti(L)(4-Cl-PhN)(py)](2)center dot Tol center dot THF (5 center dot Tol center dot THF), [Ti(L)(4-Br-PhN)(py)](2)center dot Tol (6 center dot Tol) and a (bis)ligand-coordinated complex Ti(L)(2)center dot phen (7) (py = pyridine, phen = 1,10-phenanthroline). Attempts to prepare the monomeric titianium imido complexes were unsuccessful. DFT studies show that the assumed compound which contains Ti = N species is less stable than imido-bridged Ti-N(R)-Ti complexes, providing the better understanding of the experimental results.
