Abstract

original image

Ring cyclization: A mercury-catalyzed cyclization reaction to provide 3-benzoylbenzo[b]thiophenes was achieved in good yields by treatment of 2-alkynylphenyl alkyl sulfoxides with mercury chloride and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) in benzene heated at reflux for 24 h (see scheme).
