Abstract

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 Ph₃PO. 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.
