A new sustainable strategy for the synthesis of benzoxazoles from substituted N-(2-halophenyl)benzamides was developed in which inexpensive, readily available, air-stable, recyclable copper(II) ferrite serves as a nanocatalyst. The nanocatalyst can be completely recovered with an external magnet and can be used seven times without significant loss of catalytic activity. Georg Thieme Verlag Stuttgart. New York.
