light yellow to gold-coloured liquid | [Uses]
4-Fluoroaniline is a degradation product of Ezetimibe (E975000). 4-Fluoroaniline is used as an analytical reagent in the enzymic detection of glucose. | [Uses]
Intermediate in the manufacture of herbicides and plant growth regulators. | [Definition]
ChEBI: A primary arylamine that is the derivative of aniline in which the hydrogen at position 4 has been substituted by fluorine. It is used as an intermediate in the manufacture of pharmaceuticals, herbicides and plant growth regulators. | [Preparation]
The better process in the one-step process is the nitrobenzene method, which is obtained by deoxygenation, hydrogenation and fluorination. With PdCl2-V2O5 as the catalyst and carbon monoxide as the reducing agent, the reaction was carried out at 160°C for 3h, and the yield of 4-fluoroaniline could reach 90%, with another 10% of aniline as a by-product. With PtO2 as the catalyst, BF3-HF as the fluorinating agent and hydrogen as the reducing agent, the reaction was carried out at 42℃ for 12.5h, with 100% conversion and 95% yield. | [Synthesis Reference(s)]
