11synthesis methods

Product Name:4-Fluoroaniline
CAS Number:371-40-4
Molecular formula:C6H6FN
Molecular Weight:111.12

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.

Steps:

2 4.2.2. 4-Fluoroaniline (4a)

To a solution of 4-fluoro-1-nitrobenzene (3a, 212 mL, 2.00 mmol)in MeOH (10 mL) was added 10% Pd/C (21 mg, 0.020 mmol). Thereaction mixture was stirred and bubbled with H2 at room temperaturefor 3 h. The solids were filtered off and washed with DCM(25 mL). The filtrate and DCM washing were combined andconcentrated under reduced pressure to give 4a as a clear yellow oil(222 mg, 100%).
