George Büchi
George Hermann Büchi (August 1, 1921 – August 28, 1998) was a Swiss organic chemist and professor at the Massachusetts Institute of Technology. "Paternò's reaction", known since the early twentieth century, was renamed to the "Paternò–Büchi reaction The Paternò–Büchi reaction, named after Emanuele Paternò and George Büchi, who established its basic utility and form, is a photochemical reaction, specifically a 2+2 photocycloaddition, which forms four-membered oxetane rings from an excit ..." based on enhancements made to it by Büchi's research group. Büchi died at the age of 77 of heart failure while hiking with his wife in Switzerland.

Baden, Switzerland
Baden (German for "baths"), sometimes unofficially, to distinguish it from other Badens, called Baden bei Zürich ("Baden near Zürich") or Baden im Aargau ("Baden in the Aargau"), is a town and a municipality in Switzerland. It is the main town or seat of the district of Baden in the canton of Aargau. Located northwest of Zürich in the Limmat Valley (german: Limmattal) mainly on the western side of the river Limmat, its mineral hot springs have been famed since at least the Roman era. Its official language is (the Swiss variety of Standard) German, but the main spoken language is the local Alemannic Swiss-German dialect. the town had a population of over 19,000. Geography Downtown Baden is located on the left bank of the river Limmat in its eponymous valley. Its area is divided into the Kappelerhof, Allmend, Meierhof, and Chrüzliberg. In 1962, Baden also absorbed the adjacent village of Dättwil. On the right bank of the river is the village of Ennetbaden, former ...

Organic Chemistry
Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms.Clayden, J.; Greeves, N. and Warren, S. (2012) ''Organic Chemistry''. Oxford University Press. pp. 1–15. . Study of structure determines their structural formula. Study of properties includes physical and chemical properties, and evaluation of chemical reactivity to understand their behavior. The study of organic reactions includes the chemical synthesis of natural products, drugs, and polymers, and study of individual organic molecules in the laboratory and via theoretical ( in silico) study. The range of chemicals studied in organic chemistry includes hydrocarbons (compounds containing only carbon and hydrogen) as well as compounds based on carbon, but also containing other elements, especially oxygen, nitrogen, sulfur, phosphorus (included in ...

Massachusetts Institute Of Technology
The Massachusetts Institute of Technology (MIT) is a private land-grant research university in Cambridge, Massachusetts. Established in 1861, MIT has played a key role in the development of modern technology and science, and is one of the most prestigious and highly ranked academic institutions in the world. Founded in response to the increasing industrialization of the United States, MIT adopted a European polytechnic university model and stressed laboratory instruction in applied science and engineering. MIT is one of three private land grant universities in the United States, the others being Cornell University and Tuskegee University. The institute has an urban campus that extends more than a mile (1.6 km) alongside the Charles River, and encompasses a number of major off-campus facilities such as the MIT Lincoln Laboratory, the Bates Center, and the Haystack Observatory, as well as affiliated laboratories such as the Broad and Whitehead Institutes. , 98 ...

Leopold Ružička
Leopold Ružička (; born Lavoslav Stjepan Ružička; 13 September 1887 – 26 September 1976) was a Croatian-Swiss scientist and joint winner of the 1939 Nobel Prize in Chemistry "for his work on polymethylenes and higher terpenes" "including the first chemical synthesis of male sex hormones." He worked most of his life in Switzerland, and received eight doctor ''honoris causa'' in science, medicine, and law; seven prizes and medals; and twenty-four honorary memberships in chemical, biochemical, and other scientific societies. Early life Ružička was born in Vukovar, Kingdom of Croatia-Slavonia, Lands of the Crown of Saint Stephen, Austro-Hungarian Empire (today in Croatia). His family of craftsmen and farmers was mostly of Croat origin, with a Czech great grandparent, Ružička, and a great grandmother and a great grandfather from Austria.Now available from He lost his father, Stjepan, at the age of four, and his mother, Amalija Sever, took him and his younger brother Stje ...

Edward M
Edward is an English given name. It is derived from the Anglo-Saxon name ''Ēadweard'', composed of the elements '' ēad'' "wealth, fortune; prosperous" and '' weard'' "guardian, protector”. History The name Edward was very popular in Anglo-Saxon England, but the rule of the Norman and Plantagenet dynasties had effectively ended its use amongst the upper classes. The popularity of the name was revived when Henry III named his firstborn son, the future Edward I, as part of his efforts to promote a cult around Edward the Confessor, for whom Henry had a deep admiration. Variant forms The name has been adopted in the Iberian peninsula since the 15th century, due to Edward, King of Portugal, whose mother was English. The Spanish/Portuguese forms of the name are Eduardo and Duarte. Other variant forms include French Édouard, Italian Edoardo and Odoardo, German, Dutch, Czech and Romanian Eduard and Scandinavian Edvard. Short forms include Ed, Eddy, Eddie, Ted, Teddy and Ned ...

Ernest Guenther Award
The Ernest Guenther Award in the Chemistry of Natural Products is an American Chemical Society (ACS) award in the field of the chemistry of natural products. The purpose of the award is to recognize and encourage outstanding achievements in the analysis, structure elucidation, and chemical synthesis of natural products, with special consideration given to the independence of thought and originality. The award is granted regardless of race, gender, age, religion, ethnicity, nationality, sexual orientation, gender expression, gender identity, presence of disabilities, and educational background. The award consists of $6,000, a medallion, and a certificate. The medallion is presented during an award address. The award was established in 1948 by Fritzsche Dodge and Olcott Inc. to mark the 75th anniversary of the founding of the company. Since 1969,''Fritsche Award in Essential Oils Named for Dr. Guenther.'' In: ''Journal of the American Oil Chemists' Society.'' 44, 1967, S. A626– ...

Paternò–Büchi Reaction
The Paternò–Büchi reaction, named after Emanuele Paternò and George Büchi, who established its basic utility and form, is a photochemical reaction, specifically a 2+2 photocycloaddition, which forms four-membered oxetane rings from an excited carbonyl and reacting with an alkene. : With substrates benzaldehyde and 2-methyl-2-butene the reaction product is a mixture of structural isomers: : Another substrate set is benzaldehyde and furan or heteroaromatic ketones and fluorinated alkenes. The alternative strategy for the above reaction is called the Transposed Paternò−Büchi reaction. See also *Aza Paternò−Büchi reaction - the aza-equivalent of the Paternò–Büchi reaction *Enone–alkene cycloadditions In organic chemistry, enone–alkene cycloadditions are a version of the +2cycloaddition This reaction involves an enone and alkene as substrates.
