Azide ion recognition in water–CHCl3 using a chelating phosphonium borane as a receptor

Youngmin Kim, Todd W. Hudnall, Ghenwa Bouhadir, Didier Bourissou and François P. Gabbaï

In H2O–CHCl3, the phosphonium borane [ortho-(Mes2B)C6H4(PMePh2)]+ selectively complexes azide anions to afford ortho-(Mes2(N3)B)C6H4(PMePh2) in which the boron-bound azide anion is stabilized by an interaction with the adjacent phosphorus atom.
