A convenient approach for (1,3)-1,4-diarylbuta-1,3-dienes via intermolecular Heck reaction of olefins and β-bromostyrenes promoted by μ-OMs palladium-dimer complex has been successfully developed. The products 1,4-conjugated dienes could be obtained with good yield (up to 82%). The catalyst system has excellent chemical selectivity and group tolerance which could supply an alternative way to gain the valuable biaryl linkage building blocks. Furthermore, fluorescence studies of dienes showed that some of them may have potential applications as luminescent clusters.
通过μ-OMs钯二聚体配合物促进的烯烃与β-溴苯乙烯的分子间Heck反应，成功开发了一种合成(1,3)-1,4-二芳基丁-1,3-二烯的简便方法。可以以良好的产率（高达82%）获得1,4-共轭二烯产物。该催化体系具有优异的化学选择性和基团耐受性，可为获得有价值的联芳基连接结构单元提供一种替代方法。此外，二烯的荧光研究表明，其中一些可能具有作为发光簇的潜在应用。
