In the presence of catalytic amounts of RhH(PPh3)4 and 1,2-bis(diphenylphosphino)ethane (dppe), 1,3-benzothiazoles, 1,3-benzoxazoles, and benzothiophene reacted with α-(phenylthio)isobutyrophenone giving 2-phenylthio derivatives. Reactive monocyclic heteroaromatics, 1-methyl-1,2,3,4-tetrazole and 2-cyanothiophene were also converted into the 5-phenylthio derivatives. The use of an appropriate phenylthio

A new approach to C−Scouplings is reported that relies on nickel catalysis undermildconditions, enabled by micellar catalysis in recyclable water as the reaction medium. The protocol tolerates a wide range of heteroaromatic halides and thiols, including alkyl and heteroaryl thiols, leading to a variety of thioethers in good isolated yields. The method is scalable, results in low residual metal in
Thiazoles and benzothiazoles undergo regioselective C2–H chalcogenation via the sequence of thiazole C2-functionalization with phosphines to produce phosphonium salts which in turn react with S- and Se-centered nucleophiles to give products of C2–H chalcogenation and allow for recovery of the starting phosphine. The atom economical sequence proceeds under mild conditions and features broad scope for

Aryl sulfides are synthesized by metal-free arylation of thiols with diaryliodonium salts under basic conditions. The protocol features easy performance, mildconditions, and short reaction time. It provides access to an array of products, including such that contain complex moieties of biological and therapeutic relevance (e. g., heterocycles, a carbohydrate). DFT calculations demonstrate that the
芳基硫化物是在碱性条件下通过硫醇与二芳基碘鎓盐的无金属芳基化合成的。该方案具有性能简单、条件温和、反应时间短等特点。它提供了对一系列产品的访问,包括包含具有生物学和治疗相关性的复杂部分的产品(例如,杂环、碳水化合物)。DFT 计算表明反应通过 Ar 2 I(SR) 中间体的形成进行,然后 C-S 形成还原消除。
