Synthesis, characterization and ion pairing through NMR techniques

Concerning the synthesis and characterization of new complexes of general formula (L-Au-S)X major advancements are related to the synthesis of new ligands (NHCs, NACs and phosphines) that have different stereo-electronic characteristics in order to modulate the position of the anion and the properties of the Au-S bond. Phosphines and phosphites containing different alkyl or aryl functionality are able to alter the position of the anion but, at the same time, the nature of the bond gold (Dalton Transactions 42 (2013), 4122-4131 DOI: 10.1039/C2DT32260A). Instead regarding NHCs and NACs ligands the introduction of alkyl and/or aryl functionality on the ligand is able to modify significantly the structure of ion pair but leaving unaltered the bond of the substrate to gold (Organometallics 32 (2013), 4444-4447 DOI: 10.1021/om4005912). Future developments concern the synthesis of NHC ligands containing functionalities that are able to form hydrogen bonds in order to induce a specific supramolecular structure of the catalyst.
