constrained binuclear palladium catalyst system affords selective thioetherification of a wide range of functionalized arenethiols with chloroheteroaromatic partners with the highest turnover numbers (TONs) reported to date and tolerates a large variety of reactive functions. The scope of this system includes the coupling of thiophenols with six‐ and five‐membered 2‐chloroheteroarenes (i.e., functionalized

corresponding bromo or iodo analogues by using lithium dibutyl(isopropyl)magnesate(1-) and lithium chloride under noncryogenic conditions. The procedure was optimized in terms of the choice between two magnesates and the presence or absence of lithium chloride in the reaction medium. pyridines - magnesium - lithium - organometallicreagents
