Аннотация: Chlorination of 3,5-dichloro-2,4,4,6-tetraphenyl-4H-thiopyran 1-oxide 3(CI₂ in CS₂,20°C) followed byalcoholysis (EtOH, MeOH) gives ethyl or methyl (1E,4E)-1,4,5-trichloro-1,3,3,5-tetraphenylpenta-1,4-diene-1-sulfinates 5 and 6, respectively; the structure of 5 has been determined by X-ray analysis.
