Titanium(IV) Imido Complexes of 1,3,5-Trialkyl-1,3,5-triazacyclohexanes

Abstract

Reactions of the imido complex Ti(NBu^t)Cl₂(py)₃ (py = pyridine) with 1,3,5-trialkyl-1,3,5-triazacyclo- hexanes (R₃tach) produce the corresponding imido complexes TiCl₂(NBu^t)(R₃tach) (R = Et, Bu^t). The new complexes have been characterized by n.m.r. spectroscopy and, for the R = Bu ^t case, by X-ray diffraction studies. The absence of a C_3v axis of symmetry for the new complexes allowed complete and unequivocal assignment of their ¹H n.m.r. spectra by consideration of proton{proton coupling and nuclear Overhauser effects.
