A convenient synthesis of 2-substituted benzothiazoles and benzoxazoles from the reactiono-aminophenol oro-aminothiophenol with acyl chlorides or acid anhydrides has been accomplished. The various carboxylic acid derivatives were reacted witho-aminophenol oro-aminothiophenol in the presence of KF-Al(2)O(3)as a base heterogeneous catalyst to form correspondence benzothiazoles and benzoxazoles in high yields, and the catalyst showed a good recyclability.
