Alkynyl derivatives of selenophene II. Addition of thiols to selenienyl alkynyl ketones

The reaction of selenienyl alkynyl ketones with thiophenol and butyl mercaptan gave good yields of selenienylketovinyl sulfides. The corresponding sulfones were obtained from some of the sulfides by oxidation with hydrogen peroxide. The IR spectra of the synthesized compounds are discussed.See 1] for communication I.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 12, pp. 1637–1639, December, 1971.
