Abstract :
In this study, zirconium dodecylphosphonate was synthesized by the reported method
in scientific literature. 2-Alkylbenzoxazoles were prepared from aliphatic carboxylic acids
and 2-aminophenol in the presence of this catalyst under solvent-free conditions at 100°C. Their
structures were recognized by IR, 1H NMR, and 13C NMR. Then, we used aromatic carboxylic acids
in the similar reaction. But, the results show aromatic carboxylic acids don’t react with
2-aminophenol. So, this method introduces a selective and constructive method for synthesis of
2-alkyl benzoxazoles without salt formation. On the other hand, this research offers several
advantages such as high yields, good reaction times, easy work-up and use of a safe catalyst.
