Novel indenyl ligands bearing electron-withdrawing functional groups

Abstract

A series of molybdenum complexes bearing new ligands is reported. The study covers a series of molybdenum compounds with the η⁵-coordinated indenyl ligand substituted with acyl-, ester- and amide-functions. This portfolio was extended by adding one representative with a η³-coordinated ester-substituted indenyl ligand. The functionalized indenes, necessary for the assembly, were prepared by convenient routes starting from inexpensive and readily available materials, enabling their production on a multigram scale. All structural types presented in this experimental study were supported by X-ray crystallographic data.
