Versuchsvorschrift
To a solution of 4.48 g of a cis-trans isomer mixture of 2-[3-(2-cyanoethenyl)phenyl]-[1,3]dioxolane in 100 ml of ethyl acetate was added 0.60 g of 5% palladium carbon to perform hydrogenation. The catalyst was filtered by filtration with Celite, and the filtrate was concentrated under reduced pressure to obtain 3.52 g of 2-[3-(2-cyanoethyl)phenyl]-[1,3]dioxolane.
