Several classes of ligands exhibit the ability to modify their electronic properties via nucleophilic attack or electrophilic addition at one of more of the ligand atoms. Examples of such behavior include nucleophilic attack on metal carbonyls to form acyl ligands or carbenes, as well as alkylation of metal cyanides to form the corresponding isocyanides. As part of our group's continuing interest in redox-active, main group-transition metal platforms, we have begun to investigate whether stibine ligands may display analogous behavior in conjunction with a transition metal center. Changes in the electronic properties of metal-coordinated stibines upon coordination of anions at the antimony center, as well as potential applications of these anion-induced changes will be discussed.
