The kinetics of liquid‐phase oxidation of 1‐methoxy‐2‐(1‐methylethyl)benzene ( 1a ), 1‐methoxy‐3‐(1‐methylethyl)benzene ( 1b ), and 1‐methoxy‐4‐(1‐methylethyl)benzene ( 1c ) with oxygen as oxidant to yield the corresponding 1‐methyl‐1‐(2‐methoxyphenyl)ethyl ( 2a ), 1‐methyl‐1‐(3‐methoxyphenyl)ethyl ( 2b ), and 1‐methyl‐1‐(4‐methoxyphenyl)ethyl ( 2c ) hydroperoxides was studied. The oxidizabilities of 1a , 1b , and 1c were established over the temperature range 50–120°C. The overall activation energies of oxidation were determined for 1b and 1c over the temperature range 50–120°C. Thermal stability of 2a and 2b and the initiating properties of hydroperoxides 2a , 2b , and 2c were studied. Long‐term noncatalytic oxidations of 1b and 1c to respective hydroperoxides were carried out. © 2004 Wiley Periodicals, Inc. Int J Chem Kinet 37: 10–16, 2005
