Bechamp reaction

Lianyungang Klinechem Co.,Ltd | Updated: Nov 29, 2018

In organic synthesis the Bechamp reaction, first reported in 1863 by Antoine Béchamp,[1] is used for producing arsonic acids from activated aromatic rings; for example the synthesis of arsanilic acid from aniline.[2][3][4]

 2000

The reaction is an electrophilic aromatic substitution, using arsenic acid as the electrophile. Important products of this reaction include roxarsone; which exhibits an anticoccidial action and promotes growth in animals.[5]

2001
