Synthesis, Electrochemistry, and Imido Transfer Reactions of (TTP)Ti(η2-PhNNPh)

Abstract

<p>Treatment of (TTP)Ti(η2-RC⋮CR) (R = Et or Ph) with PhNNPh results in formation of the azobenzene adduct (TTP)Ti(η2-PhNNPh) (<strong>1</strong>) in good isolated yield. Complex <strong>1</strong> reacts with (TTP)Ti(η2-RC⋮CR) at elevated temperatures to cleanly afford 2 equiv of the phenylimido compound, (TTP)TiNPh (<strong>2</strong>). The azobenzene complex, <strong>1</strong>, is also formed in low yields by the reaction of the (TTP)TiNPh (<strong>2</strong>) with excess 1,2-diphenylhydrazine. The electrochemistry of the azobenzene adduct (<strong>1</strong>) and the phenylimido complex (<strong>2</strong>) is investigated by cyclic voltammetry experiments.</p>
