Darstellung
synthetischeA catalyst was prepared by dissolving 0.1 g of palladium in 10 ml. of pyridine, adding 10 ml. of silica gel particles to the solution, and evaporating the mixture to dryness. The obtained catalyst (10 ml.), 20 ml. of tert-butylbenzene, and 10 ml. of acetic acid were enclosed in a microbomb having an inner volume of 50 ml., and ethylene and oxygen were introduced into the bomb in terms of a pressure of 10 kg/cm2 and 30 kg/cm2, respectively, from the upper valve. The reaction was carried out at 150°C for 5 hours with laying said bomb in an oil bath equipped with a shaking means. tert-Butylstyrene was yielded in a proportion of 470 %, based on the mole of palladium in the used catalyst.
