A highly efficient metal-free intermolecular C(sp3)âC(sp3) allylâallyl cross-coupling protocol between allyl acetates and allyltrimethylsilanes, which proceeded smoothly in the presence of catalytic triflimide to form 1,5-dienes with good to excellent regioselectivity, has been developed.

Cinnamyltrimethylsilane underwent desilylation via one-electron oxidation with VO(OEt)Cl2, which was applied to the cross-coupling with the less oxidizable allylic silanes to give the corresponding 1,5-hexadienes. Chlorination or aromatization based on desilylation was observed on treatment of benzyltrimethylsilane or 3-ethoxycarbonyl-2-methyl-5-trimethylsilyl-5-phenyl-4,5-dihydrofuran with VO(OEt)Cl2-Me3SiOTf, respectively.
