Versuchsvorschrift

29.1 g of bicyclohexyl-4,4'-dione and 123 g of propyl-triphenylphosphonium bromide were suspended in 300 ml of THF. The solution was cooled to 0° C., and a solution of 36 g of potassium tert-butoxide in 100 ml of THF was added dropwise, and the mixture was stirred at RT overnight. Conventional work-up gave 4,4'-dipropylidenebicyclohexyl.
