  ## Notable work
  
  The Sommelet–Hauser rearrangement is a named reaction based on the work of Hauser and Sommelet involving the rearrangement of certain benzyl quaternary ammonium salts. The reagent is sodium amide or another alkali metal amide and the reaction product a N,N-dialkylbenzylamine with a new alkyl group in the aromatic ortho position. For example, benzyltrimethylammonium iodide, $[(C_6H_5CH_2)N(CH_3)_3]I,$ rearranges in the presence of sodium amide to yield the o-methyl derivative of N,N-dimethylbenzylamine.
