Treatment of 1 with the strong Lewis acid B(C6F5)3 results in decomposition, however the milder borane BPh3 produces the capped species 3, which is inert with respect to reaction with H2. Complex 1 does not react with the sterically encumbered BMes3, but exposure of that mixture to H2 produces the amide complex 4 with concomitant formation of the radical anion complex 5. Addition of H2 to 1 produces the amide complex 6, and subsequent treatment with BMes3 produces 4 and 5. Treating 4 with HCl produces NH3. B15C5 = benzo-15-crown-5 ether. Mes = 2,4,6-trimethylphenyl.
