Reaction of a magnesium diboranate complex with triphenylphosphine oxide provides a terminal magnesium boryl, which is itself a potent reagent for the deoxygenative reduction of PhPO. Computational analysis with density functional theory (DFT) indicates that B-B bond activation results from initial coordination of the P[double bond, length as m-dash]O bond of the phosphine oxide to magnesium.
一种二硼酸镁配合物与三苯基氧化膦反应生成一种末端硼化镁，其本身是用于PhPO脱氧还原的有效试剂。采用密度泛函理论（DFT）进行的计算分析表明，B-B键活化源于氧化膦的P=O键与镁的初始配位。
