1-Chloro-4-(4-fluorophenyl)-3-butene → 1,1'-(4-Chlorobutylidene)bis(4-fluorobenzene)

Participants

Reaction Steps

A suspension of 150 g of 4,4-bis-(4-fluorophenyl-3-butenylchloride, 1 l isopropyl alcohol, and 10 g of 10% palladium-on-charcoal was shaken at room temperature under 40 psi of hydrogen. The uptake of hydrogen ceased after about 5 hrs. The mixture was filtered and the solvent was evaporated to provide an oil. Distillation provided 140.2 g (92.8%) of 4,4-bis-(4-fluorophenyl)butylchloride, bp 155°-158° (1.3 mm).
