From oxygen atom transfer by stibine oxide to hydroxo–antimony formation <i>via</i> Lewis acid capture
We report an improved synthesis of the Lewis acid-stabilized stibine oxide Ph<sub>3</sub>SbOB(C<sub>6</sub>F<sub>5</sub>)<sub>3</sub> (1) and show that it undergoes oxygen-atom transfer to PPh<sub>3</sub>. The reaction proceeds through a discrete Ph<sub>3</sub>Sb·B(C<sub>6</sub>F<sub>5</sub>)<sub>3</sub> Lewis pair, which we have isolated and characterized in solution, and which also mediates trace-water activation to give the hydroxo-antimony(III) adduct (2). These results reveal that suitably polarized stibine oxides can access OAT reactivity not observed in bulky analogues, broadening the chemistry of heavy p-block oxides.
