Unusual, Thermally Stable, Sublimable Aminoboranes B(NHAr)X2 (X = Cl, F, or NH2); X-Ray Crystal Structure of Bis(amino)(2,4,6-tri-t-butylphenylamino)borane, B(NH2)2(NHAr)

The sterically demanding 2,4,6-tri-t-butylamido ligand (N-HAr) confers unexpected thermal stability on the title boranes B(NHAr)X2 , each of which is sublimable without elimination of HX; the difluoroborane (3) has significant BN double-bond character as is evident from magnetically distinct F- ligands, only one of which (presumably the trans) is coupled to the NHAr proton; compound (4) has trigonal planar boron with one of the B-NH2 bonds significantly longer than the other, 1.470(4) and 1.437(4) Angstroem, and each longer than B-NHAr, 1.412(4) Angstroem.
