A Novel Route to Pentamethylcyclopentadienyllutetium Alkoxides and Thiolates

Abstract

A folded Lu(μ-S)2Li four-membered ring is present in the complex 1, in which a hard metal of the lanthanoid series is complexed by a ligand that is bound via the soft element sulfur to the metal. The synthesis of 1 was accomplished by reaction of the (μ-CH3)2-analogue with tBuSH.
