Cross-coupling reaction of organoalane reagents with 2-mercaptobenzo-5-membered heterocycles for efficient synthesis of benzo-5-membered heterocycle sulfides
A highly efficient and simple route for the synthesis of benzo-5-membered heterocycles sulfides has been developed by the cross-coupling reaction of 2-mercaptobenzo-5-membered heterocycles with (hetero)arylaluminum reagents. Various benzo-5-membered heter
Substrate-promoted ligand-free CuI catalyzed S-arylation of 2-mercaptobenzothiazoles with aryl iodides in water
A green and efficient method has been developed for the cross-coupling of 2-mercaptobenzothiazoles with aryl iodides in water. The reactions proceeded smoothly under ligand-free conditions in the presence of TBAB to give the corresponding products in good yields. The protocol showed good tolerance toward a variety of functional groups. A substrate-promoted mechanism for this catalytic reaction has been proposed.
Copper(I)-catalyzed cascade synthesis of 2-substituted 1,3-benzothiazoles: Direct access to benzothiazolones
An efficient cascade process for the preparation of 2-substituted 1,3-benzothiazoles directly from 2-haloaryl isothiocyanates and O or S nucleophiles by a Cu-catalyzed, intramolecular, C-S bond formation has been developed. This cascade method is viable f

Intra- and Intermodular C-S bond formation using a single catalytic system: First direct access to arylthiobenzothiazoles
We have for the first time developed two llgand-assisted Cu(I)-catalyzed sequential Intra- and intermolecular 5-arylations leading to the direct synthesis of arylthiobenzothlazoles In one pot without an Inert atmosphere. Low catalyst loading, inexpensive
