A versatile and efficient Pd(OAc)2/1,1'-bis(diisopropylphosphino)ferrocene-catalyzed cross-coupling of thiols with aryl halides was developed. Aryl bromides and chlorides can be coupled to aliphatic and aromatic thiols - the widest substrate scope of any reported to date. This catalyst system also enables the coupling of secondary phosphines with aryl halides.
