Evaluation of Pd→B Interactions in Diphosphinoborane Complexes and Impact on Inner‐Sphere Reductive Elimination

The dative Pd→B interaction in a series of (R)DPB(R’) Pd(0) and Pd(II) complexes ((R)DPB(R’)=(o‐PR(2)C(6)H(4))(2)BR’, diphosphinoborane) was analyzed using XRD, (11)B NMR spectroscopy and NBO/NLMO calculations. The borane acceptor discriminates between the oxidation state Pd(II) and Pd(0), stabilizi...

description The dative Pd→B interaction in a series of (R)DPB(R’) Pd(0) and Pd(II) complexes ((R)DPB(R’)=(o‐PR(2)C(6)H(4))(2)BR’, diphosphinoborane) was analyzed using XRD, (11)B NMR spectroscopy and NBO/NLMO calculations. The borane acceptor discriminates between the oxidation state Pd(II) and Pd(0), stabilizing the latter. Reaction of lithium amides with [((R)DPB(R’))Pd(II)(4‐NO(2)C(6)H(4))I] chemoselectively yields the C−N coupling product. DFT modelling indicates no significant impact of Pd(II)→B coordination on the inner‐sphere reductive elimination rate.
