To a solution of 0.52 g of 4,4-diphenylbut-1-ene in 25 mL of dichloromethane at 0° C. was added 0.75 g of 50-60% by wt of m-chloroperbenzoic acid. The mixture was stirred at room temperature overnight, then heated at reflux for 1 hr. Water, 1 mL, and 0.25 g of sodium hydrogen sulfite were added to destroy the excess oxidizing agent. The organic layer was washed with water and dilute sodium hydrogen carbonate solution, dried, then concentrated in vacuo to give 0.5 g of 4,4-diphenylbut-1-ene oxide which is characterized by:
