<p><b>Halaman baru</b></p><div>'''Penataan ulang Bamberger''' merupakan [[reaksi kimia]] antara N-fenilhidroksilamina dengan asam kuat, membentuk senyawa 4-aminofenol. Nama reaksi ini berasal dari kimiawan Jerman [[Eugen Bamberger]] (1857–1932).<br />
<br />
<br />
N-fenilhidroksilamina umumnya disintesis dari [[nitrobenzena]] melalui [[redoks|reduksi]] menggunakan [[rodium]] atau [[seng]].<br />
<br />
== Mekanisme reaksi ==<br />
Mekanisme penataan ulang Bamberger dimulai dari monoprotonasi N-fenilhidroksilamina '''1'''. N-protonasi '''2''' lebih difavoritkan, tetapi ia tidak akan menghasilkan apa-apa. O-protonasi '''3''' dapat menghasilkan [[ion nitrenium]] '''4''', yang kemudian dapat bereaksi dengan nukleofil ([[air|H<sub>2</sub>O]]) dan membentuk senyawa [[4-aminofenol]] '''5'''.<br />
