| Abstract: | Perfluoroalkyl (RF) titanocene reagents Cp2TiIIIRF] synthesized via Cp2TiIIICl] rather than Cp2TiII] show new types of perfluoroalkylation reactions. The Cp2TiIIIRF] reagents exhibit a wide variety of reactivity with carbonyl compounds including esters and nitriles, and selectivities far higher than those reported for conventional RFLi and RFMgX reagents. |
