We demonstrate that a titanium-carbon multiple bond, specifically an alkylidyne ligand in the transient complex, (PNP)TiCtBu (A) (PNP - = N[2-P(CHMe2)2-4-methylphenyl]2), can cleanly activate methane at room temperature with moderately elevated pressures to form (PNP)TiCHtBu(CH3). Isotopic labeling and theoretical studies suggest that the alkylidene and methyl hydrogens exchange, either via tautomerization invoking a methylidene complex, (PNP)TiCH 2(CH2 tBu), or by forming the methane adduct (PNP)TiCtBu(CH4). The thermal, fluxional and chemical behavior of (PNP)TiCHtBu(CH3) is also presented in this study. © The Royal Society of Chemistry 2011. Source
