Procedure

A mixture of 3 mmol of cis-decalin, 18 mmol of biacetyl, 0.3 mmol of N-hydroxyphthalimide, 0.015 mmol of cobalt (II) acetate, and 3 ml of acetic acid was stirred at 75° C. under an oxygen atmosphere (1 atm) for 8 hours. Products in the reaction mixture were found, by gas chromatographic analysis, to be 4a-acetyl-cis-decalin (yield 24%), 4a-hydroxy-cis-decalin (yield 4%), 4a,8a-dihydroxy-is-decalin (yield 22%), and 1,6-cyclodecanedione (yield 10%), at a conversion rate from cis-decalin of 67%.
