“…For structure analysis, see: Cremer & Pople (1975); Iulek & Zukerman-Schpector (1997). For details of synthesis, see: Bradscher et al (1954); Zukerman-Schpector, Maganhi et al (2006); Drabowicz & Mikolajczyk (1978).…”

“…The starting 2-(4-methoxyphenylthio)cyclohexanone was prepared from the reaction of 2-chlorocyclohexanone and 4methoxythiophenol as previously reported (Bradscher et al 1954). The sulfoxide 2-[(4-methoxybenzene)sulfinyl]cyclohexanone was prepared by oxidation of 2-(4-methoxyphenylthio)cyclohexanone (Zukerman-Schpector, Maganhi et al 2006;Drabowicz & Mikolajczyk, 1978). A CH 3 OH (10 ml) solution of SeO 2 (1.23 g, 11.08 mmol) and hydrogen peroxide (30% H 2 O 2 in aqueous solution; 1.25 ml, 11.08 mmol) was added drop-wise, at 273 K, to a solution of 2-(4-methoxyphenylthio)cyclohexanone (2.62 g, 11.08 mmol) in CH 3 OH (5 ml).…”
