All three C−H bonds of a methyl group are activated in the reaction of [Cp( i Pr 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.
