A ruthenium catalyst forms carbon-carbon bonds between olefins and alcohols while liberating only water as a by-product. Alkenes and alcohols are among the most abundant and commonly used organic feedstock in industrial processes. We report a selective catalytic alkylation reaction of alkenes with alcohols that forms a carbon-carbon bond between vinyl carbon-hydrogen (C–H) and carbon-hydroxy centers

Fe(OTf) 3 -catalyzed reaction of benzylic acetates withallyltrimethylsilane, azidotrimethylsilane, and cyanotrimethylsilane affordedthe corresponding allylated, azido, and cyano products in high yields.2-Trimethylsilyl-substituted benzofuran and indole worked well tofurnish the benzyl-substituted benzofuran and indoles.
