Polymer (PVP) supported ferric chloride catalyzes efficiently the condensation of o-phenylenediamines with ketones under solvent free conditions to afford the corresponding 1,5-benzodiazepine derivatives in high yields. The reaction proceeds efficiently under ambient conditions giving excellent yields (85-96%). (C) 2004 Published by Elsevier B.V.
