Abstract
Abstract Copper-catalyzed one-pot three-component reactions of 2-iodoanilines, aldehydes, and NaSH· n H 2 O afford benzothiazoles in good yields. When CuCl was employed as a catalyst in the absence of a ligand, a variety of aromatic aldehydes and substituted 2- iodoanilines reacted with NaSH· n H 2 O to produce the corresponding 2-arylbenzothiazoles in 70–98% yields. The copper catalyst plays a key role in C–S bond formation between ...
