Participants

Reaction Steps

44 g (0.127 mol) of 4-bromo-1,1-bis(4-methoxyphenyl)-butene were dissolved in 160 ml of ethanol, 2.8 g of palladium-on-charcoal (10%) were added and hydrogenation was carried out in a shaking vessel at room temperature in the course of about 2 hours. The catalyst was then filtered off with suction, the filtrate was concentrated and the crude product was purified by fractional distillation. 34.4 g of a fraction were obtained at 220°-226° C./-0.2 mm.
