Versuchsvorschrift

10.50 g (0.04 mol) of 1-methyl-1-phenylundecyl alcohol was dissolved in 50 ml of dichloromethane, cooled in ice bath, 10.6 ml (12.29 g, 0.08 mol) of trimethylsilyl bromide was added and the mixture stirred for 1 h under protection from moisture. The solution was diluted with 100 ml ether and washed four times with 50 ml water, brine, dried and evaporated to give crude 2-phenyl-2-bromododecane. 35 ml of 2.3 M hydrogen peroxide in THF (0.08 mol) was added to the 2-phenyl-2-dodecyl bromide and the mixture was cooled on ice bath. 8.84 g (0.04 mol) of silver trifluoroacetate was added. 70 ml of conc. NaHCO3 was added and the mixture filtered. The reaction flask and the filter cake was rinsed with diethyl ether. The aqueous phase was separated and the organic phase washed with conc. NaHCO3, 50 ml water, brine, dried and evaporated to give an oil. The oil was purified by flash chromatography using 2:8 ether:pentane as eluent. The yield of 1-methyl-1-phenylundecyl hydroperoxide was 30%.
