The stable metallocene-butyl complexes [(CpMe)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 (CpMe)3M with IMes resulted in a normal-to-abnormal NHC rearrangement.
