Abstract

In a single step, several variously functionalized [RuCp*(η^6^‐arene)]^+^ sandwich complexes have been prepared starting from RuCl~3~·__x__H~2~O in yields ranging from 35 to 80%, referring to ruthenium. The protocol covers the preparation of valuable [RuCp*]^+^‐complexed amino acids. In comparative experiments starting from the oligomer [RuCp*Cl~2~]~n~ and using methanol/methanolate as the reducing agent, the formation of undesired side products was observed, resulting from nucleophilic substitution at the o‐chloroanisole complex and from methoxylation of the Cp* ligand.
