Abstract
Protonation of MeRNH center dot BH3 (R = Me or H) with HX (X = B(C6F5)(4), OTf, or Cl), followed by immediate, spontaneous H-2 elimination, yielded the amine-boronium cation salt [MeRNH center dot BH2(OEt2)][B(C6F5)(4)] and related polar covalent analogs, MeRNH center dot BH2X (X = OTf or Cl). These species can be deprotonated to conveniently generate reactive aminoborane monomers MeRN=BH2 which oligomerize or polymerize; in the case of MeNH2 center dot BH3, the two step process gave poly(N-methylaminoborane), [MeNH-BH2](n).
