Under palladium(II)-catalyzed and oxidative conditions, the coupling of furans with styrenes leads to the formation of Heck-type products in medium to good yields. The reaction is highly regio- and stereoselective, giving trans-olefins predominantly.

CH vs. CBr in Heck: The direct dehydrogenative coupling of furans and thiophenes with styrenes occurs under mild conditions (see scheme). This method allows the coupling of brominated substrates through CH bond activation. In addition, DMSO and benzoquinone had a positive effect on the reaction rate.
