Synthesis and photoluminescent properties of conjugated aryl-vinyl dioctyl 2,6-dimethylbenzofuro[5,6-b]furan-3,7-dicarboxylate derivatives

The synthesis of highly fluorescent conjugated benzodifuran aryl-vinyl systems, containing four double bonds and at least four phenyl rings, is described. The ethyl groups of diethyl 2,6-dimethylbenzofuro[5,6-b]furan-3,7- dicarboxylate, obtained by the Michael type condensation of p-benzoquinone and ethyl acetoacetate, were replaced by octyl groups via the transesterification reaction to improve the desired product solubility in common organic solvents. The dioctyl ester was brominated and used for the Wittig reaction with stilbene aldehydes, obtained by the Heck reaction of 4-bromobenzaldehyde and an appropriate styrene. The products, obtained in 48-92% yield, exhibit the UV-Vis fluorescence with high quantum yields, 58-69%.

Palladium-catalyzed heck reaction of aryl chlorides under mild conditions promoted by organic ionic bases

An efficient Pd-catalyzed Heck reaction of aryl chlorides with olefins under mild conditions is described. High yields of products were achieved with n-Bu4N+OAc- as base. Significantly, the temperature of the Heck reaction of diverse nonactivated aryl chlorides can be lowered to 80 °C. The new reaction system can also tolerate a wider range of olefins.
