Baeyer, Johann Friedrich

Baeyer, Johann Friedrich Wilhelm Adolf von (1835-1917) German chemist who devoted his life to the analysis and synthesis of organic molecules and published more than 300 important papers. He is especially noted for his studies of uric acid and organic dyes. His synthesis of indigo was of great commercial importance, and for this achievement he was awarded the Nobel Prize in chemistry in 1905.

While we think of blue jeans as the quintessential American item of clothing, it was the contributions of the German chemist Johann Friedrich Wilhelm Adolf von Baeyer that put the blue" in blue jeans and enabled this image of American culture to flourish.

Johann Friedrich Wilhelm Adolf von Baeyer (1835-1917) was hom in Germany. He discovered barbituric acid—the first of a group of sedatives known as barbiturates— in 1864 and named it after a woman named Barbara. Who Barbara was is not certain. Some say she was his girlfriend, but because Baeyer discovered barbituric acid in the same year that Prussia defeated Denmark, some believe he named the acid after Saint Barbara, the patron saint of artillerymen. Baeyer was the first to synthesize indigo, the dye used in the manufacture of blue jeans. He was a professor of chemistry at the University of Strasbourg and later at the University of Munich. He received the Nobel Prize in chemistry in 1905 for his work in synthetic organic chemistry.

Although Chapter 17 discussed several oxidation reactions, an important reaction was not discussed in that chapter. Section 17.3 discussed the oxidation of an alkene to an epoxide using a peroxyacid such as 163 (also see Chapter 10, Section 10.5). Peroxyacids also react with ketones to form esters in what is known as the Baeyer-Villiger reaction. This reaction is named in honor of its discoverers, Johann Friedrich Wilhelm Adolf von Baeyer (Germany 1835-1917) and Victor Villiger (Switzerland 1868-1934). 

Johann Friedrich Wilhelm Adolf von Baeyer (1835-1917) studied under Bunson and Kekuld at the University of Heidelberg and Hofmann at the University of Berlin (from which he received the doctorate). Victor Villiger was von Baeyer s student. As an interesting footnote, although this work was first published in 1899, it received little attention presumably because suitable peracids were not widely available. Baeyer, A. Villiger, V. Chem. Ber., 1899, 32, 3625. A review has appeared see Krow, G. R. Org. React.,1992., 43,25Ut...

The excellence of German chemistry in general, not just of its organic branch, is objectively attested by its share of Nobel Prizes during the first two decades of the award s existence. Of the seventeen prizes awarded between 1901 and 1921 nine were to German chemists Hermann Emil Fischer (1902), Johann Friedrich Wilhelm von Baeyer (1905), Edward Buchner (1907), Wilhelm Ostwald (1909), Otto Wallach (1910), Alfred Werner (1913), Richard Will-statter (1915), Fritz Haber (1918), and Walther Nemst (1920).
