Reaction Steps

A mixture of 1-(hex-5-ynyl)-4-n-propyl-2-oxa-6,7-dithiabicyclo-[2.2.2]octane (0.75 g., 1 equivalent), anhydrous sodium acetate (2.0 g.) and 3-chloroperbenzoic acid (85%, 1.12 g. 2.5 equivalents) was stirred at 20° in dry acetonitrile (50 ml.) for 18 hours. Water was added and the mixture was extracted with ethyl acetate. The extracts were washed with sodium hydrogen carbonate solution, water and dried over anhydrous magnesium sulphate. The solvent was removed in vacuo. After purification by chromatography on silica (eluting with ethyl acetate), 1-(hex-5-ynyl)-4-n-propyl-2-oxa-6,7-dithiabicyclo[2.2.2]octane-6-oxide was obtained as a colourless solid (0.35 g.).
