Titanium-Thiolate-Aluminum-Carbide Complexes by Multiple C-H Bond Activation.
All three C-H bonds of a methyl group are activated in the reaction of [Cp(iPr(3)PN)Ti(SR)(2)] with AlMe(3) [Eq. (1)]. The Ti-Al-carbide clusters formed contain a severely distorted tetrahedral carbide carbon atom with a relatively short bond to Ti, which is attributed to a relative increase in the Lewis acidity of the Ti center as a result of the interaction of the S and N donors with Al.
