Staudinger, Hermann Nobel prize

Furfuryl mercaptan (= Furanmethanthiol) (furan thiol) Coffea spp. (coffee seed) (Rubiaceae) [from roasted coffee] identified by Hermann Staudinger (Germany, Nobel Prize, Chemistry, 1953, polyisoprenoids coined term macromolecule ) OD-R (coffee odour)... 

Early in the last century, the Nobel Prize winning chemist Hermann Staudinger discovered a reaction between phosphines and azides, which became known as the Staudinger reaction (Staudinger and Meyer, 1919). Triphenylphosphine reacts with azides to form an intermediate iminophosphorane with the release of nitrogen gas. This intermediate quickly breaks down in aqueous environments to yield triphenylphosphine oxide and a primary amine (Figure 17.17). 

Hermann Staudinger received the Nobel Prize in Chemistry in 1953 for his work on macromolecules. The award not only acknowledged the contributions of the man who first proposed use of the name "macromolecules" (57), but recognized the field of macromolecular chemistry. In his address to Staudinger for the award of the Nobel Prize, A. Fredga said ... 

Staudinger, H. Ber. Dtsch. Chem. Ges. 1907, 40, 1145. Hermann Standinger (Germany, 1881-1965) won the Nobel Prize in Chemistry in 1953 for his discoveries in the area of macromolecnlar chemistry. 

This review is dedicated to the memory of the eminent and ingenious scientist Professor Dr. Hermann Staudinger (Nobel prize for Chemistry, 1953), who among other numerous very important findings, discovered the iminophosphoranes.

Leopold Stephen Ruzicka (1887-1976) was bom in Vukovar, Croatia. Though few in his family had much formal schooling, he nonetheless decided to study chemistry and ultimately received his Ph.D. in 1910 at the University of Karlsruhe with Hermann Staudinger. He followed Staudinger to the Swiss Federal Institute (E.T.H.) in Zurich and later became professor there (1929-1957). He was the first to show that rings of more than eight carbons are possible, and he opened up the entire field of ter-pene chemistry. With Adolf Butanandt of Germany he received the 1939 Nobel Prize in chemistry. 

Staudinger, Hermann. (1881-1965). A German chemist, winner of a Nobel Prize in 1953 for his pioneer work on the structure of macromolecules and polymerization. A large part of modem high-polymer chemistry is based on his original research. 

Staudinger, Hermann (1881-1965). Fundamental research on high-polymer structure, catalytic synthesis, polymerization mechanisms, resulting eventually in development of stereospecific catalysts by Ziegler and Natta (stereoregular polymers). Nobel Prize 1963. 

Hermann Staudinger, who pioneered polymer chemistry and won the 1953 Nobel Prize in chemistry (Chemical Fleritage Foundation)... 

Staudinger, Hermann (1881—1965) In 1920 Hermann Staudinger, a German chemist, put forward a theory about the chemical nature of a whole group of substances that were natural and synthetic. He called them macromolecules or the giant molecules. Today we tend to call them polymers. It took 15 years to persuade his fellow chemists of the validity of his theory. His theory explained the nature of plastics and also indicated the ways in which they could be made. It provided the foundation for the world of plastics as we know it. In 1953 he received the Nobel Prize. 

Hermann Staudinger (1881-1965) Professor at the University of Freiburg, Germany, Nobel Prize for Chemistry in 1953. 

Hermann Staudinger (1881-1963). German chemist. One of the pioneers in polymer chemistry. Staudinger was awarded the Nobel Prize in Qiemistry in 1953. 

Leopold Ruzicka, a student of Hermann Staudinger, received the Nobel Prize in 1939 for disproving BaeyeFs strain theory by demonstrating that the active components of musk and civet were cyclic ketones with 16 and 17 carbon atoms in the rings. Ziegler employed the Ru hi dilution principle in the condensation of... 

Polymer Science—The Gateway to the Polymer Age, In 1920, an event occurred that set the stage for the rapid development of polymeric materials. In that year, a German chemist, Hermann Staudinger, proposed that polymers were truly macromolecules. His successful efforts to prove this hypothesis were the catalyst for a burst of scientific endeavor that ultimately brought us into the Polymer Age. It is somewhat ironic that Staudinger finally received a Nobel Prize in chemistry in 1953, many years after his outstanding efforts. 

From the time of Hermann Staudinger s enunciation of the macromolecular hypothesis in 1920, polymer science and engineering has had many fundamental advances leading to the understanding of plastics, rubber, adhesives, coatings, and fibers of today. The discoveries that these Nobel Prize winners made are summarized in Table C5.3.1 (C1,C2). These people have revolutionized life in the modern world.
