Hydrogen atom abstraction atomic transfer kinetics

The trityl radical is able to abstract a hydrogen atom from OsH2(CO)4, yielding the 17-electron OsH(CO)4, which rapidly dimerizes to Os2H2(CO)g [33]. Although this intermediate was not directly observed, kinetic evidence is in agreement with the proposed hydrogen atom transfer mechanism [34,35]. [Pg.144]

The growing polymer chain may also be terminated by abstraction of a hydrogen atom from any suitable donor molecule called telogen (S-H). In these instances, hydrogen transfer from the telogen to the growing radical produces a dead polymer macromolecule and a new free radical [Eq. (13.46)]. The latter can add to ethylene and start a new chain [chain termination with kinetic chain transfer Eq. (13.47)] ... [Pg.745]
