1H-2-benzothiopyrans and 1H-2-benzothio-pyrylium salts based on bis(arylmetylthio)acetylenes

Article abstract of DOI:10.1080/10426509908546507

The intramolecular cyclization of bis(arylmethylthio)acetylenes by electrophiles like ICl, Br₂, POCl₃, and Ph₃C⁺BF₄^- to substituted 1H-2-benzothiopyrans, -thiopyrylium salts and in a specific case to a 2-thiaspiro[5,4]-deca-3,6,9-trien-8-one is described.
