    • This cycle is strongly supported by the rate law shown in eq 4. According to the rate-determining-step approximation d[H2]/d t = k [ 4 ], where [ 4 ] = [ 1 ]-[ 2 ]-[ 3 ]. However [ 2 ] = [ 4 ]·[H2BNH2]/ K 1· K 2·[BH3NH3] ≈ 0 and [ 3 ] = [ 4 ]·[H2BNH2]/ K 2 ≈ 0 because the species H2BNH2 polymerizes. Thus, [ 4 ] = [ 1 ] and d[H2]/d t = k [ 1 ].

    • note
    • An on-metal polymerization process should involve that [ 1 ] = [ 4 ] + [ 5 ], with 5 being the metal species responsible of the polymerization, and therefore, the rate law of eq 4 should not be possible.
