Catching the anchor : Although diboranes(4) commonly react by way of BB bond activation, reaction of B 2 Mes 2 Br 2 with [Pt(PEt 3 ) 3 ] led to the selective oxidative addition of one BBr bond; the resulting diboran(4)yl complex shows an unexpected dative PtB bonding interaction to the second boron center of the diboran(4)yl ligand. Oxidative addition of one BBr bond in B 2 (NMe 2 ) 2 Br 2 to [Pt(P i Pr 3 ) 2 ] enabled the isolation of a diboran(4)yl species without any dative PtB interaction.
