Title: Process for preparing tert-butylstyrene

Abstract: TERT-Butylstyrene is prepared by a one-step reaction of tert-butylbenzene, ethylene and oxygen in the presence of a catalyst prepared by treating metallic palladium or fatty acid salts thereof with pyridine. The yield is increased by using together therewith a promoter prepared by treating one or more metals or oxides or fatty acid salts thereof, the metals being selected from the group consisting of copper, nickel, manganese, uranium and thallium. The reaction is carried out at a temperature between 50.degree. to 300.degree.C under a pressure of up to 100 kg/cm.sup.2.
