Abstract

In fluorinated alcohols, the cationic Rh (I) species, which is derived from [Rh (COD) Cl] 2 and AgSbF6, efficiently catalyzed intramolecular [4+ 2] cycloaddition reactions of ester-tethered 1, 3-diene-8-yne derivatives. The catalytic system was also effective in intramolecular [5+ 2] cycloaddition reactions of ester-tethered ω-alkynyl vinylcyclopropane compounds.
