A green approach for the synthesis of 2-substituted benzoxazoles and benzothiazoles via coupling/cyclization reactions
We have developed the green method for the synthesis of benzoxazoles and benzothiazoles with moderate to good yields using imidazolium chlorozincate (II) ionic liquid supported into Fe3O4 nanoparticles (LAIL@MNP) under solvent-free sonication. The reaction was performed under mild conditions and onl...
