A study was carried out on the kinetics of free‐radical chain oxidation of 1‐isopropyl‐4‐methoxybenzene ( 1a ) and 1‐ethyl‐4‐methoxybenzene ( 1b ) with oxygen in the liquid phase to yield 1‐methyl‐1‐(4‐methoxyphenyl)ethyl hydroperoxide ( 2a ) and 1‐(4‐methoxyphenyl)ethyl hydroperoxide ( 2b ). The oxidizability of 1a and 1b was studied over the temperature range 50–100°C. Long‐term oxidations of 1a and 1b to the corresponding hydroperoxides were carried out and the properties and thermal stability of 2a were established. © 2002 Wiley Periodicals, Inc.
