A mild convenient ultrasound assisted synthesis of 2-aryl benzoxazoles catalyzed by KCN/MWCNT as an efficient heterogeneous nanocatalyst

159 The combined effect of ultrasounds and multi-walled carbon nanotubes was used for efficient and rapid preparation of benzoxazole derivatives through the reaction of 2-aminophenol and aromatic aldehydes. This reaction was efficiently catalyzed by MWCNTs supported KCN as a heterogeneous nanocatalyst under ultrasonic irradiations.
