Catalytic Dehydrogenation of (Di)Amine-Boranes with a Geometrically Constrained Phosphine-Borane Lewis Pair
10.1021/acscatal.8b00152 2018-04-18 The o-phenylene bridged phosphine-borane iPr2P(o-C6H4)B(Fxyl)2 2 was prepared. Despite ring strain, it adopts a closed form, as substantiated by NMR, XRD, and DFT analyses. However, the corresponding open form is only slightly higher in energy. The dormant Le... |
