Versuchsvorschrift

A mixture of 2 mmol of 2-octene (a mixture of cis- and trans-isomers), 10 mmol of tetralin, 0.2 mmol of N-hydroxyphthalimide, 0.1 mmol of molybdenum hexacarbonyl, 0.002 mmol of cobalt (II) acetate, and 2 ml of acetonitrile was stirred at 70° C. under an oxygen atmosphere (1 atm) for 5 hours. Gas chromatographic analysis of products in a reaction mixture revealed that 2-octene was converted, at a rate of 56%, into 2,3-epoxyoctane in yield of 49%. In this connection, tetralin was found to be converted, at a rate of 23%, into α-tetralol (yield: 7.7%) and α-tetralone (yield: 10%).
