Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 2-Ethylbenzo[d]oxazole, is researched, Molecular C9H9NO, CAS is 6797-13-3, about Zirconium dodecylphosphonate: selective and constructive catalyst for preparation of 2-Alkyl benzoxazoles from aliphatic carboxylic acids.Related Products of 6797-13-3.
In this study zirconium dodecylphosphonate prepared by literature methods have been used as catalyst for the preparation of 2-alkylbenzoxazoles. 2-Alkylbenzoxazoles were prepared from aliphatic carboxylic acids and 2-aminophenol under solvent-free conditions at 100°. The reaction was tested with aromatic carboxylic acids but the results showed that they could not react with 2-aminophenol. So, this method introduces a selective and constructive method for synthesis of 2-alkylbenzoxazoles 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.
