通过[Cp 2 Ti III Cl]而不是[Cp 2 Ti II ]合成的全氟烷基(R F)钛茂试剂[Cp 2 Ti III R F ]显示了新型的全氟烷基化反应。[Cp 2 Ti III R F ]试剂与包括酯和腈在内的羰基化合物具有广泛的反应性,其选择性远远高于传统R F Li和R F MgX试剂的报道。
Paradigm Shift from Alkaline (Earth) Metals to Early Transition Metals in Fluoroorganometal Chemistry: Perfluoroalkyl Titanocene(III) Reagents Prepared via Not Titanocene(II) but Titanocene(III) Species
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.
