Reaktionsschritte

In a four-necked flask of 200 ml provided with a stirrer was charged 33.7 g of an aqueous solution of 30% potassium hydroxide, to which was added a mixture of 22.1 g of 95% 1-phenylcyclohexyl hydroperoxide and 30 g of benzene while the liquid temperature was maintained at 10° C. with stirring. Furthermore, 19.1 g of neodecanoyl chloride was added dropwise over 7 minutes while the liquid temperature was maintained at 15° C. with stirring. After the liquid temperature was raised to 25° C. and the stirring was continued for 2 hours, 40 g of cold water was added and further the stirring was made for 5 minutes. The water phase was separated and washed with an aqueous solution of 40 g of 5% sodium hydroxide and further with water three times. The solution was dried on magnesium sulfate anhydride and benzene was removed off under vacuum to obtain 24.0 g of a desired compound as a light yellow liquid. This compound had an active oxygen amount of 4.20%, a purity of 91% through calculation and a yield of 63 mol %.
