Participants

Reaction Steps

1,1-diphenyl-4-bromobutene (10.0 g) is dissolved in absolute ethanol (100 ml) and palladium on carbon (400 mg) is added. The reaction mixture is placed under hydrogen atmosphere (P=3.3 bar) for 6 hours. The mixture is filtered on kelite, the filtrate is concentrated to obtain the desired product as an orange oil (9.24 g).
