The cross-couplingreaction of allylic carbonates with organosilanes was found to proceed without fluoride ion activation under mild conditions by using a coordinatively unsaturated palladium complex as a catalyst. The reaction was assumed to proceed through an allylpalladium alkoxide derived from the allylic carbonate substrate and a palladium(0) species, the alkoxo ligand activating the organosilicon

Cross-coupling and carbonylative cross-coupling of organofluorosilanes with hypervalent iodonium tetrafluoroborates
The palladium-catalyzed cross-coupling and carbonylative cross-coupling of aryl-, alkenyl-, and alkynylfluorosilanes promoted by fluoride ion with hypervalent aryl-, alkenyliodonium tetrafluoroborates were achieved at room temperature under an atmospheric pressure of carbon monoxide.
