Reactions of B(2)(o‐tolyl)(4) with Boranes: Assembly of the Pentaborane(9), HB[B(o‐tolyl)(μ‐H)](4)

Reactions of the diborane(4) B(2)(o‐tolyl)(4) and monohydridoboranes are shown to give B(o‐tolyl)(3) and (o‐tolyl)BR(2) (R(2)=(C(8)H(14)) 3, cat 4, pin 5, (C(6)F(5))(2) 6) as the major products. The corresponding reaction with BH(3)‐sources gives complex mixtures, resulting from hydride/aryl exchang...

description Reactions of the diborane(4) B(2)(o‐tolyl)(4) and monohydridoboranes are shown to give B(o‐tolyl)(3) and (o‐tolyl)BR(2) (R(2)=(C(8)H(14)) 3, cat 4, pin 5, (C(6)F(5))(2) 6) as the major products. The corresponding reaction with BH(3)‐sources gives complex mixtures, resulting from hydride/aryl exchange, dimerization and borane elimination. This led to the isolation of the first tetra‐substituted pentaborane(9) HB[B(o‐tolyl)(μ‐H)](4) 8. The reaction pathways are probed experimentally and by computations.
