Abstract
Readily available cinnamic acid derivatives such as ferulic acid couple with beta-bromostyrenes and 1-bromo-4-phenylbutadiene under palladium catalysis accompanied by decarboxylation to produce the corresponding alpha,omega-diarylbutadienes and -hexatrienes, respectively. Some of the products exhibit solid-state fluorescence.
摘要
在钯催化作用下，肉桂酸衍生物（如阿魏酸）与β-溴代苯乙烯和 1-溴-4-苯基-1,3-丁二烯发生偶联反应，并伴随着脱羧反应，分别生成相应的α,ω-二芳基-1,3-丁二烯和-1,3,5-己三烯。部分产物具有固态荧光。
