Abstract: The reductions of N-arylfluorenlmines by Hantzsch ester in the presence andabsence of Mg2+ have been studied. The similar reductions by BNAHhave been compared.The results show that (1) Mg2+ plays a role of electrophilic catalyst; (2) the strongerreduction ability of Hantzsch ester than BNAH Is the result of electrostatic effect caused by its3,5-carbonyl oxygens which decreases the energy of the transition state more effectively;(3) one-step hydride transfer mechanism has been proposed.
Key words: Hantzsch ester, BNAH, Imines, Structure-reactivity relationship, One-step hydride transfer mechanism
