The Hofmann–Martius rearrangement in

catalyst is an acid like hydrochloric acid.[1][2]

The Hofmann–Martius rearrangement

When the catalyst is a metal halide the reaction is also called the Reilly–Hickinbottom rearrangement.[3]

The reaction is also known to work for aryl ethers and two conceptually related reactions are the

Friedel–Crafts alkylation
.

In one study this rearrangement was applied to a 3-N(CH3)(C6H5)-2-oxindole:[4][5]

The reaction is named after German chemists August Wilhelm von Hofmann and Carl Alexander von Martius.
