The reaction is also known as the Bart reaction. The Scheller modification, on the other hand, involves diazotizing primary aromatic amines in the presence of arsenious chloride and trace amount of cuprous chloride, CuCl, and can be used for producing arylarsenic acids. The Scheller modification is essentially a modified version of the Bart reaction.
