Coordination chemistry of gold catalysts bearing eight different ligands [L=PPh 3 , JohnPhos ( L2 ), Xphos ( L3 ), DTBP, IMes, IPr, dppf, S ‐tolBINAP ( L8 )] has been studied by NMR spectroscopy in solution at room temperature. Cationic or neutral mononuclear complexes LAuX (L= L2 , L3 , IMes, IPr; X=charged or neutral ligand) underwent simple ligand exchange without giving any higher coordinate complexes. For L2 AuX the following ligand strength series was determined: MeOH≪hex‐3‐yne
