Herein, we report the gold-catalyzed deallylative C-S cross-coupling reaction through ligand-enabled Au(I)/Au(III) redox catalysis. One of major challenges in reactions is to prevent catalyst deactivation caused by formation a strong gold-sulfur bond. We discovered that use allyl phenyl sulfide as sulfur surrogate facilitates dynamic equilibrium between cationic Au(I) and Au(I)-sulfide complexes, overcoming gold quenching problem. A detailed mechanistic investigation, including 31P NMR studies, mass analysis, stoichiometric experiments, provided valuable insights into mechanism, which further supported computational studies.
