18e Cp*W(NO)(CH2CMe3)(η3-allyl) complexes effect concurrent N−H and α-C−H bond activations of cyclic, saturated amines under mild conditions, the conversions involving pyrrolidine being shown. In a similar manner, treatment of Cp*W(NO)(CH2CMe3)(η3-3,3-Me2C3H3) with piperidine at room temperature results in the clean formation of the alkyl amido complex, Cp*W(NO)(CH2CMe3)(NC5H9CMe2CHCH2).
