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

Organosilanes serve as precursors to organocopper intermediates in a copper‐catalyzed addition to vinylepoxides (see scheme). Ligand structure has a significant effect on the reactivity of the organocopper intermediate, and the catalysis proceeds without the need for a stoichiometric silane activator such as fluoride.
