Synthesis and catalytic activity of dinuclear imido titanium complexes: the molecular structure of [Ti(NPh)Cl(μ-Cl)(THF)2]2

Reaction of TiCl4 with the reagents RN(SiMe3)2 in dichloromethane precipitates red to black powders (R = 1-adamantyl, phenyl, pentafluorophenyl, 3,5-bis(trifluoromethyl)phenyl), which on treatment with tetrahydrofuran give the new THF adducts [Ti(NR)Cl(μ-Cl)(THF)2]2.
