The transient titanium alkylidyne, (PNP)TiCtBu (PNP = N[2-PiPr2-4-methylphenyl]2), activates a C–H bond of ethane at room temperature, and a β-hydrogen of the resulting ethyl ligand is subsequently transferred to the adjacent alkylidene ligand to form an ethylene adduct of titanium. Treatment of the ethylene complex with two-electron oxidants such as organic azides results in extrusion of ethene concomitant with formation of a mononuclear titanium imido complex.
