Abstract

The stable metallocene-butyl complexes [(Cp^Me)₂M(ⁿBu)]₂ (M = Y, Dy) were synthesized and their reactivity towards to ferrocene and bulky N-heterocyclic carbenes investigated. Selective mono-deprotonation of ferrocene and a benzylic methyl group of IMes were observed, whereas a control reaction of (Cp^Me)₃M with IMes resulted in a normal-to-abnormal NHC rearrangement.
