Hydrogen Peroxide → HCID 21427688, compound

Participants

Reaction Steps

Hydrogen peroxide (2.1 ml. of 30%, 18.3 mmoles) in glacial acetic acid (15 ml.) was added dropwise to a stirred solution of 2,5-dimethylcyclohexyl isopropyl sulphide, prepared as in Part A above (3.4 g., 18.3 mmoles) in glacial acetic acid (25 ml.). Heat was evolved initially and the resulting solution was stirred overnight at room temperature. The reaction mixture was poured into ferrous sulphate solution (800 ml.) and extracted with ether three times. The combined extracts were washed twice with N NaOH solution, water, and then dried (MgSO4). Removal of the solvent left a colourless oil (3.6 g.) which was purified by column chromatography, on silica gel eluting with CHCl3, (the product has a t.l.c. Rf 0.2 on silica gel, eluting with CHCl3) to yield 2,5-dimethylcyclohexyl isopropyl sulphoxide. (Found: C, 65.1; H, 10.8. C11H22OS requires C, 65.3; H, 10.9%) as a viscous oil which shows a strong S=O stretching frequency at 9.5-9.9 microns in the I.R.
