Hauser was a member of the National Academy of Sciences[1][2] and a professor of chemistry at Duke University.[3] Notable workThe Sommelet–Hauser rearrangement is a named reaction based on the work of Hauser[4] and Sommelet[5] involving the rearrangement of certain benzyl quaternary ammonium salts.[6][7] 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.[4] AwardsHis contributions were recognized by the following awards:[1]
