Lanthanide–tungsten heterobimetallic complexes viaσ-bond metathesis
Abstract
Reactions of [{Ln(C5Me5)2H}2](Ln = Y, Sm) with [W(C5H5)2H2] afford the σ-bond metathesis products [(C5Me5)2Ln(µ-η1, η5-C5H4)(µ-H)2W(C5H5)], via dehydrocoupling between the Ln–H bond and the C–H (but not the weaker W–H) bond of [W(C5H5)2H2].
