Facile Formation of Chloro−η3-Allyl Complexes by Reaction of Vinyldiazoacetates and Ruthenium(II) Arene Complexes

Abstract

The reaction of vinyldiazoacetates 1 and ruthenium arene complexes 2 at room temperature resulted in the formation of a new type of chloro-substituted η3-allyl ruthenium complexes, 3, in high yield. The structure of 3a was determined by X-ray crystallographic analysis. The reaction of the ruthenium complexes 3a,d with styrene demonstrated that these complexes are capable of inducing a cyclopropanation reaction.
