実験手順

0.3 mmol of N-hydroxyphthalimide and 0.3 mmol of Co(II) acetate are added at a temperature of 125° C. to 30 mmol of cumene in a round-bottomed flask having an attached reflux condenser. The reaction mixture is stirred for 8 hours at said temperature under an oxygen atmosphere of 1 bar. Not the target product, but acetophenone is obtained at a selectivity of 58.7%, 2-phenyl-2-propanol (13.1%) and phenol (10.4%) at a cumene conversion rate of 49.3%.
