An efficient synthesis of 1,5-benzodiazepines from o-phenylenediamine and ketones under solvent-free conditions in the presence of a catalytic amount of HBF4-SiO2 is discussed. Cyclic and acyclic ketones reacted smoothly to furnish high yield of the products with selectivity in short reaction time. (c) 2006 Elsevier B.V All rights reserved.
