During the nineteenth century it was widely believed—incorrectly as we 11 soon see— that cycloalkane rings are planar A leading advocate of this view was the German chemist Adolf von Baeyer He noted that compounds containing rings other than those... 

The reaction of ketones with peroxy acids is both novel and synthetically useful An oxygen from the peroxy acid is inserted between the carbonyl group and one of the attached car bons of the ketone to give an ester Reactions of this type were first described by Adolf von Baeyer and Victor Vilhger m 1899 and are known as Baeyer—Villiger oxidations... 

Barbituric acid was first pre pared in 1864 by Adolf von Baeyer (page 112) A histori cal account of his work and the later development of barbiturates as sedative-hypnotics appeared in the October 1951 issue of the Journal of Chemical Education (pp 524-526)... 

Adolf von Baeyer (1835-1917) was born in Berlin, Germany, and received his Ph.D. at the University of Berlin in 1858, working with Robert Bunsen and August Kekuie. After holding positions at Berlin and Strasbourg, he was a professor at Munich from 1875 to 1917. He was the first to synthesize the blue dye indigo and was also discoverer of the first barbiturate sedative, which he named after his friend Barbara. Baeyer was awarded the Nobel Prize in chemistry in 1905.

In the autumn of 1907, he started to study chemistry at the Institute chaired by Adolf von Baeyer at the University of Munich, where he passed the first Verband s examination after three semesters. In 1909, he continued his studies at the University of Berlin, gaining his doctorate in 1911 under Emil Fischer. The subject of his doctoral dissertation was Syntheses of Certain New Glucosides. The tremendous personality of Emil Fischer left its mark on Helferich for the rest of his life. In conversation with Helferich, one was often aware of the great veneration he always felt for his tutor and mentor. 

The Baeyer-Villiger oxidation reaction was discovered more than 100 years ago by Adolf von Baeyer and Victor Villiger. By this reaction, ketones are converted into the corresponding esters. In organic chemistry, peracids are commonly used as catalyst to perform this atypical oxidation reaction that results in oxygen insertion into a carbon—carbon bond (Fig. 1).

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. 

While correlating the stability of the ring with their size Adolf von Baeyer advanced in 1885 his famous strain theory. We know that the four valencies of a carbon atom go to the four comers... 

Kipping, a Manchester native, studied with Roscoe and Schorlemmer, then spent a year (1886) in Munich at Adolf von Baeyer s laboratory where Perkin, Jr., was Privatdozent and von Baeyer s assistant. Kipping completed his London doctoral degree in 1887 and was Armstrong s assistant from 1890 to 1897. See Partington, A History of Chemistry, IV 851. And Robert Robinson, Memoirs, 2223. 

Phenolic resins. The oldest condensation reaction on record is between phenol and formaldehyde to produce phenolics. Professor Adolf von Baeyer first documented the reaction in 1872, for which the Nobel Committee awarded him their prize in 1905. Thirty years later, a technical application of this reaction was worked out by Dr. Leo Baekeland, when he showed that useful moldings can be made by carrying out the final stages of the reaction under pressure. As his reward, phenolic resins are still often called Bakelite, a seemingly better deal chan Baeyer s. At one time, phenolics were the workhorse of the plastics industry. 

Friedlander, P. Ber. Dtsch. Chem. Ges. 1882, 15, 2572. Paul Friedlander (1857-1923), born in Kdnigsberg, Prussia, apprenticed under Carl Graebe and Adolf von Baeyer. He was interested in mnsic and was an accomplished pianist.
