Abstract

A selective, TBHP/KI-promoted C-O bond cleavage of ethers followed by annulation with anilines and elemental sulfur provides a wide range of 2-aryl-, 2-heteroaryl-, and 2-alkyl-substituted benzothiazoles with satisfactory yields and good functional group compatibility under transition-metal-free conditions.
