The stepwise palladium-catalyzed coupling of dibromo-1,6-methano[10]annulene derivatives to a phenyl-acetylene substituted by an electron-withdrawing group followed by coupling with a phenylacetylene possessing an electron-donating group allows the preparation of donor/acceptor systems which contain three aromatic moieties linked by ethynediyl bridges. The same type of cross-coupling starting from 2-ethynyl-1
将二溴1,6-甲基[10]环戊烯衍生物逐步钯偶联至被吸电子基团取代的苯基乙炔,然后与具有供电子基团的苯基乙炔偶联,可以制备供体/受体包含通过乙炔基桥连接的三个芳族部分的体系。从2-乙炔基-1,6-甲基[10]环戊烯和溴取代的偶氮苯衍生物开始的相同类型的交叉偶合可轻松获得新型的偶氮染料。将这些化合物的性质与仅包含苯环的类似化合物的性质进行比较。
