摘要：
An arylvinyl bromide bearing a long-chain alkoxy group reacts with arylacetylenes in the presence of a palladium catalyst to give liquid-crystalline 1,4-diaryl-1-buten-3-yne derivatives. The new liquid-crystalline compounds with a conjugated enyne core show mesogenic phases at a wide range of temperature.
