Gentle thermolysis of the 18e alkyl-allyl complex, Cp*W(NO)(CH2CMe3)(η3-3,3-Me2C3H3) (1), generates a reactive 16e allene intermediate, Cp*W(NO)(η2-CH2=C=CMe2) (A), with the concomitant evolution of neopentane via hydrogen abstraction from the dimethylallyl ligand. A has been structurally characterized as its PMe3 adduct and is capable of effecting single and multiple C-H bond activations of hydrocarbon solvents. For example, the thermal reaction of 1 with cyclohexane leads to the formation of the 18e cyclohexenyl hydrido complex, Cp*W(NO)(η3-C6H9)(H) (5), as a result of three successive C-H activations of the alkane solvent.
