different starting materials for the preparation of dibenz[b,f][1, 4]oxazepine (, CR) were reinvestigated. The possibility of trans-cis conversion of the Schiff base (produced from and ) is considered the favorable orientation that leads to cyclization (production of ). Fluoro derivative of afforded excellent and more convenient conditions for the one pot preparation of high yield pure . The presence

Thermolysis of polyfluorinated o-hydroxybenzylidenanilines leads to cyclization via intramolecular dehydrofluorination. This reaction affords a convenient method for the preparation of hitherto unknown polyfluorodibenz [b,f][1,4] oxazepines.
