Reaction Conditions

Reaction Steps

A mixture of 35.0 g (78.7 mmol) of di-(2,2,6,6-tetramethyl-piperidin-4-yl) isophthalate, 47.3 g (472 mmol) of 90% aqueous t-butyl hydroperoxide, 2.0 g of molybdenum trioxide, and 300 ml of cyclohexane is heated two hours at 140° C. in a Fischer-Porter bottle. The red reaction mixture is treated with an additional 20.0 g (90%, 200 mmol) of t-butyl hydroperoxide and heated at 140° C. for 120 minutes to discharge the red color. The reaction mixture is cooled, filtered, and the filtrate is evaporated to an oil which is crystallized from ethanol to afford 36.2 g (72% yield) of a white solid, m.p. 135°-141° C.
