Oxidation-products of (e)-1-phenylsulfonyl-1,2-bis(phenylthio)ethylene

The crystal structures of (E)-l-phenylsulfonyl-l-phenylsulfinyl-2-phenylthioethylene, 2-phenylsulfonyl-2-phenylthio-3-phenylsulfinyl oxirane (2α, 3α) and 2-phenylsulfonyl-2,3-bis(phenylsulfinyl) oxirane (2α, 3β), which are three of the products derived from the oxidation of the title compound with a deficiency of m-chloroperbenzoic acid, have been determined. The substances crystallize in the following symmetries and cell parameters: (C20Hi6O3S3): triclinic, space group PI, a = 10.697(3), b = 10.127(3), c = 9. 724(3) Å., α = 103.1(1)° ß = 110.2(1)°, γ = 77.6(1)°,Z = 2, Dc = 1.399 g cm−3. (C20H16O4S3): triclinic, space group P[FORMULA OMITTED], a = 12.107(3), b = 9.962(3), c = 8.907(3) Å, α = 112.7(1)°, ß = 98.5(1), γ = 91.9(1)°, Z = 2, Dc = 1.433 g cm−3. (C20H16O5S3): triclinic, space group P[FORMULA OMITTED] a = 12.076(3), b = 9.996(3), c = 8.867(2) Å, α = 112.6(1)°, ß = 98.6(1)°, γ = 92.2(1)°, Z = 2, Dc = 1.476 gcm−3, V = 971.95 Å3. © by R.
