C-S cross-coupling of aryl halides with alkyl thiols catalyzed by in-situ generated Ni (II) N-heterocyclic carbene (NHC) complexes is investigated. Good to excellent yields can be obtained for a variety of aryl halides when using 5 mol% of the Ni (II)-NHC catalyst and 1.5 eq. of KOtBu. Both the electronic and steric effects of the NHC ligands on the catalytic performance of Ni (II)-NHC, as well as the

A mild, efficient, highlyselective, and environmentally friendly oxidation of sulfides to sulfoxides with a recyclable ion-supportedhypervalentiodinereagent has been developed. This reaction is tolerant of hydroxyl, nitrile, methoxy, carbon-carbon double bonds, and ester functionalities. Aliphatic and aromatic sulfides are selectively oxidized to the corresponding sulfoxides at room temperature

efficient catalytic method for the preparation of S‐aryl isothiouronium salts, and demonstrate that these air‐stable, odorless solids serve as user‐friendly sources of thiophenols in synthesis. Diverse isothiouronium salts featuring synthetically useful functionality are readily accessible by nickel‐catalyzed C−S cross‐coupling of (hetero)aryliodides and thiourea. Convenient, chromatography‐free isolation
