摘要：
The hydrosilylation/reduction of tertiary and secondary phosphine oxides to phosphines is catalyzed by B(C6F5)(3) or electrophilic fluorophosphonium cations (EPCs). B(C6F5)(3) is an effective catalyst for phosphine oxide reduction using (EtO)(3)SiH, PhSiH3, and Ph2SiH2 at elevated temperature (105 degrees C), while EPCs effect the same reduction at significantly lower temperature with PhSiH3 as reducing agent, allowing for good functional-group tolerance.
