Phenyldithiocarbamates: Efficient Sulfuration Reagents in the Chan–Lam Coupling Reaction
Cheng, Yu,Liu, Xing,Dong, Zhi-Bing
, p. 815 - 820 (2018)
The Chan–Lam coupling reaction starting from phenyldithiocarbamates and phenylboronic acids is reported. To avoid using the volatile, hazardous, and foul-smelling thiols, which are sometimes expensive and not sufficiently available, phenyldithiocarbamates can be employed. They are demonstrated to be good sulfuration reagents in the Chan–Lam coupling to prepare biaryl sulfides. By using this protocol, dithiocarbamate substrates with a wide range of functional groups including electron-rich and electron-deficient ones are explored to obtain the desired substituted biaryl sulfides smoothly. This method is ligand-free, has a broad substrate scope, enables good yields, and is easy to perform. It provides a facile and convenient preparation of biaryl sulfides.

A diverse range of o-arylthio-substituted diaryl ethers has been synthesized by direct oxythiolation of arynes with diaryl sulfoxides that involves the formation of the C-O and C-S bonds followed by migratory O-arylation.
Recyclable heterogeneous supported copper-catalyzed coupling of thiols with aryl halides: base-controlled differential arylthiolation of bromoiodobenzenes

experimental part, p. 2369 - 2378 (2009/12/28)
Alumina-supported copper sulfate efficiently catalyzes the 5-arylation of aromatic, heteroaromatic and aliphatic thiols with aryl as well as heteroaryl halides under aerobic, ligand-free conditions. This protocol provides an easy access to a variety of thioethers as well as unsymmetrical bis-thioethers by base-controlled differential coupling of thiols with iodo- and bromo-substituents in an aromatic halide. The catalyst is inexpensive, non-air sensitive, environmentally friendly and recyclable.
