Synthesis of dicyclopentadienyl ytterbium benzoate derivatives

Abstract

Title compounds Cp2YbO2CC6H4R-2 (I, R = EtO, PrO, Cl, Br, iodo, anilino) were prepared in 36-60% yield by stirring Cp2YbCl with 2-RC6H4CO2Na in THF at room temperature for 12 h. I were dimers with O-substituted benzoate ions as bridging groups and all the compounds were more stable than the parent compound Cp2YbOBz.
