Claisen, Rainer Ludwig

Claisen, R. L. Lowman, O. Ber. Dtsch. Chem. Ges. 1887, 20, 651. Rainer Ludwig Claisen (1851—1930), bom in Cologne, Germany, probably had the best pedigree in the history of organic chemistry. He apprenticed under Kekule, Wohler, von Baeyer, and Fischer before embarking on his own independent research. 

One of the earliest accounts of the tetrahedral intermediate came from Rainer Ludwig Claisen in 1887. In the reaction of benzyl benzoate with sodium methoxide and methyl benzoate with sodium benzyl oxide, he observed a white precipitate which under acidic conditions yields benzyl benzoate, methyl benzoate, methanol, and benzyl alcohol (Scheme 7.69).
