Mechanistic Insight into the Reduction of Tertiary Phosphine Oxides by Ti(O<i>i</i>Pr)₄/TMDS

Abstract

The reduction mechanism of tertiary phosphine oxides by Ti(O&lt;i&gt;i&lt;/i&gt;Pr)&lt;sub&gt;4&lt;/sub&gt;/hydrosiloxane was studied. Strong improvement was achieved using a drying agent. ESR spectra of the reaction mixture give evidence for a single electronic transfer (SET) mechanism.
