Abstract

Abstract Cinnamyltrimethylsilane underwent desilylation via one-electron oxidation with VO (OEt) Cl 2, 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) Cl 2-Me 3 SiOTf, respectively.
