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, [(C6H5CH2)N(CH3)3]I, rearranges in the presence of sodium amide to yield the o-methyl derivative of N,N-dimethylbenzylamine.




Awards


His contributions were recognized by the following awards:

1957 the Florida Section Award
1962 the Herty Medal
1967 the Medal for Synthetic Organic Chemistry from the Synthetic Organic Chemical Manufacturers' Association
