Reactions of dichlorodiphenoxotitanium(IV)

Abstract

Spectroscopic data confirm for solution the structure found in the solid state for {TiCI₂(OPh)₂}₂. The compound has been reduced by alkali metals and a number of compounds which have Ti–H bonds and contain dinitrogen when reductions are carried out under nitrogen have been studied. Examples are {Ti(OPh)₂}₂H(N₂) and {Ti(OPh)₂}₃H. Ti(OPh)₂CL₂ also reacts with (Me₃SiCH₂)₂ Mg to give Ti(OPh)₂(CH₂SiMe₃)₂.

On the basis of i.r. and n.m.r. spectra and, where paramagnetic, electron paramagnetic resonance spectra of the compounds, very tentative suggestions of structures are made. The lack of crystallinity precludes structural determination.
