Synthesis and Characterization of Gold Silyl Compounds with Different Phosphine or Phosphite Groups for Reduction Reactions

Abstract

The synthesis and structural characterization of metalloid gold clusters stabilized by sulfur ligands has increased massively in the last decade. The metalloid gold clusters are synthesized via a reduction of a gold precursor and most metalloid gold clusters are stabilized via aryl thiolate ligands. It is also possible to use thiosilyl or phosphine groups as stabilizing ligands. Here, we present a small Au6 cluster as a possible intermediate of the formation of large metalloid clusters, together with the synthesis of a variety of defined AuI precursors that contain a phosphine or a phosphite group as well as a thiosilyl ligand, which can be further used for the synthesis of metalloid gold clusters.
