Methane activation and exchange by titanium-carbon multiple bonds

Author affiliations

Abstract

We demonstrate that a titanium-carbon multiple bond, specifically an alkylidyne ligand in the transient complex, (PNP)Ti[triple bond, length as m-dash]CtBu (A) (PNP = N[2-P(CHMe2)2-4-methylphenyl]2), can cleanly activate methane at room temperature with moderately elevated pressures to form (PNP)Ti[double bond, length as m-dash]CHtBu(CH3). Isotopic labeling and theoretical studies suggest that the alkylidene and methyl hydrogens exchange, either viatautomerization invoking a methylidene complex, (PNP)Ti[double bond, length as m-dash]CH2(CH2tBu), or by forming the methane adduct (PNP)Ti[triple bond, length as m-dash]CtBu(CH4). The thermal, fluxional and chemical behavior of (PNP)Ti[double bond, length as m-dash]CHtBu(CH3) is also presented in this study.
