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.
在氟化醇中,衍生自[Rh(COD)Cl] 2和AgSbF 6的阳离子Rh(I)物种有效地催化了酯束缚的1,3-二烯-8-的分子内[4 + 2]环加成反应。炔衍生物。该催化体系在酯系的ω-炔基乙烯基环丙烷化合物的分子内[5 + 2]环加成反应中也很有效。
