Said catalyst solution and 20 ml. of tert-butylbenzene were enclosed in a microbomb having a volume of 100 ml. and ethylene and oxygen were introduced into the bombe in terms of pressure of 10 kg/cm2 and 30 kg/cm2, respectively, from the upper valve. The reaction was carried out at 120°C for 16 hours laying said bomb in an oil bath equipped with a shaking means. tert-Butylstyrene was yielded in a proportion of 1500 %, based on the mole of palladium in the catalyst used.
