Abstract

The synthesis of a germanium(IV) Lewis acid bearing tris(3,5-dimethylpyrazolyl)borate (TpMe2) and its ability to promote phosphine oxide reduction is presented. A reaction between GeCl4 and KTpMe2 resulted in TpMe2GeCl3, which upon treatment with AgOSO2CF3 yielded TpMe2Ge(OSO2CF3)3. Despite possessing similar Lewis acidity compared to the previously reported Sn(IV) analogue, TpMe2Ge(OSO2CF3)3 exhibits higher efficiency in promoting the reduction of phosphine oxides to the corresponding phosphines using phenylsilane as the reductant.
