One-electron oxidation of the β-diketiminate titanium(III) bis-neopentyl complex (Nacnac)Ti(CH2 t Bu)2 (Nacnac = ArNC(Me)CHC(Me)NAr, Ar = 2,6-(CHMe2)2C6H3) promotes α-abstraction to afford the rare and terminal four-coordinate neopentylidene (Nacnac)TiCH t Bu(OTf), which was structurally characterized. Alkylidene (Nacnac)TiCH t Bu(OTf) reacts cleanly with benzophenone and the imine functionality of the Nacnac ligand to afford the corresponding Wittig-type products.
