Abstract

Reaction of aminoboranes H2B=NR2 (R=iPr or Cy) with the cationic Cp*IrIII phosphoramidate complex [IrCp*{κ2-N,O-Xyl(N)P(O)(OEt)2}][BArF4] generates the aminoborane complexes [IrCp*(H){κ1-N-η2-HB-Xyl(N)P(OBHNR2)(OEt)2}][BArF4] (R=iPr or Cy) in which coordination of a P=O bond with boron weakens the B=N multiple bond. For these complexes, solution- and solid-state, as well as DFT computational techniques, have been employed to substantiate B−N bond rotation of the coordinated aminoborane.
