The three-coordinate titanium(III) complex Ti(N[R]Ar)3 (R = C(CD3)2CH3, Ar = 3,5-C6H3Me2) abstracts chlorine from WCl4(DME) (DME = 1,2-dimethoxyethane) in tetrahydrofuran (THF) to give yellow crystalline WCl3(THF)3 in 65% isolated yield. Orange TiCl(N[R]Ar)3, which can be recycled to Ti(N[R]Ar)3 in 73% yield by reduction with sodium amalgam, was recovered in 71% yield. WCl3(THF)3 was characterized by elemental analysis, SQUID magnetic susceptibility measurements, 1H NMR spectroscopy and single crystal X-ray crystallography. WCl3(THF)3 was found to be an octahedral complex possessing a meridional arrangement of ligands, as has been seen for other MCl3(THF)3 complexes (M = Sc, Ti, V, Cr, Mo).
