An aryne reaction with alkynyl sulfides affords benzo[b]thiophenes in a one-step simple procedure.

An efficient synthetic method of aromatick etones through CÀFc leavage of trifluoromethylg roup is disclosed. The highf unctional group tolerance of the transformationa nd the remarkable stabilityo ft rifluoromethylg roup in various reactions enabledm ulti-substituted aromatic ketone synthesis in an efficient route involving useful transformationss uch as ortho-lithiation,a ryne chemistry,a nd cross-couplings.

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.
