One-Electron Reduction of Ti(IV) Complex by Dialkylaluminum(I) Anion Giving the Ti(III) Species
Kengo Sugita, Makoto Yamashita
Abstract
A reaction of dialkylalumanylpotassium with Ti(OiPr)4 was investigated. The alumanyl anion worked as a reducing reagent to afford the trivalent titanium complex as a contact ion pair with aluminate anion probably via single-electron transfer. The ESR spectrum revealed the delocalization of an unpaired electron over Ti and Al atoms. The DFT calculations provided information about the ratio of unpaired electrons on Ti and Al atoms and the UV–vis absorption spectrum.
