Abstract

The catalytic mechanism of the organo-mediated Beckmann rearrangement has been modeled using DFT calculations. Five representative promoters were shown to be initiators rather than catalysts. A self-propagating mechanism is shown to be energetically much more favored than the previously proposed mechanisms involving a Meisenheimer complex.
